Here it is, folks. The final chapter.

Leave a review after reading, please.

NOTE: Italics mean narration by Barry Allen.

"Some friendships feel like they'll last forever and others end far too soon. Not every friendship is meant to last forever. What does last forever is the pain once that person is gone." - Barry Allen/The Flash

"I need to believe that no matter what happens in our lives, no matter how much darkness infects us, I need to believe that we can come back from that." - Oliver Queen/Green Arrow

"Dying is a lot easier than getting back up when the world's ended. You have to get up. You have to go on." - Kara Zor-El/Kara Danvers/Supergirl

It took about a week, but Team Flash, Team Arrow, Team Legends, and Supergirl managed to save every survivor in Central City. Black Siren is locked up in A.R.G.U.S. Golden Glider is behind bars in Iron Heights. Doctor Light chose to be locked away in Iron Heights because she believes paying for her crimes was her first step in redeeming herself, all thanks to her Earth-1 counterpart talking some sense into her while she was being treated on the Waverider.

Barry Allen asked for Caitlin Snow to have a proper funeral, but a cop named Matthew Paulson secretly destroyed the body by blowing it up. Fortunately, Green Arrow and the recently-recovered Speedy tracked him down. When interrogated, he said, "That monster doesn't deserve a funeral. She killed my wife, and left my son motherless." He was immediately sent to Iron Heights.

Barry, however, was in a state of depression because there was no body to bury at the funeral.

At S.T.A.R. Labs hanger, Team Flash and Team Arrow were gonna say goodbye to Team Legends because they have to return to their mission of destroying the Spear of Destiny. However, four NSA vehicles arrived. Flash, Kid Flash, Jesse Quick, Green Arrow, Speedy, Arsenal, and Spartan cover their faces with their masks/cowls/helmets. Agent Smith and a dozen armed agents come out of the vehicles.

"What are you doing here?" asked Nate.

The armed agents accompanying Smith took out their guns and aimed at the costumed vigilantes.

"Hello, Dr. Heywood," greeted Smith.

"Don't 'Dr. Heywood' me," said Nate, ticked off.

"I thought I'd come and congratulate Earth's greatest heroes for cleaning up Killer Frost's mess," said Smith, pretending to be honest.

"I think you're here to cover up our operations," guessed Nate. "You're not covering this up. Central City and Star City are both in ruins, and we want them to know that we'll always be there to keep them safe."

"You don't exactly have authority over me," said Smith. "I would also like to mention that the President ordered me to detain you, seeing as your actions have resulted in the destruction of two cities."

"You're lying," said Green Arrow.

"Why would I lie?" asked Smith, pretending to be innocent.

Supergirl approaches Smith, looking at him with contempt.

"Because Vice President Susan Brayden contacted us through Felicity Smoak and informed us of your off-the-books operation here," said Supergirl. "She's not really a big fan of your operations. By the way, she loved my pitch about reassigning you to Antarctica."

"Without the President's approval?" questioned Smith.

Supergirl takes her hands out from behind her back and shows Smith the file labeled "Project Double-Zero". It had the President's signature on it.

"The Green Arrow threatened to reveal to the world about his decision to approve the use of such a devastating weapon," said Supergirl. "So, we do have his approval about reassigning you."

Angered, Smith gives an order. "Shoot them."

All the agents fired their guns. Luckily, the three speedsters manage to catch all the bullets and disarm the agents. Suddenly, three gunshots were heard from the distance. One of them hit Felicity's iPad, causing her to drop it.

"Snipers," said Green Arrow.

"On it," said Flash, Kid Flash, and Jesse Quick at the same time.

While the speedsters take care of the snipers, the rest of their allies handled the agents. Green Arrow easily takes out one agent with a few punches, a couple of kicks, and a bow to the face. Arsenal and Speedy both fired arrows, badly wounding two agents. Spartan punches one agent in the face before grabbing his head and kneeing him in the face. White Canary engages one agent with her batons. Atom punches one agent repeatedly and then hits him in the back of the knee, knocking him down. Jefferson dodges an agent's punches and then punches him in the face as hard as he can. Captain Cold uses his Cold Gun to glue one agent to the side of a van. Citizen Steel turns himself into steel as an agent punched him, hurting him, and then punches back. With the power of the gorilla, Vixen grabs an agent and tosses him right above a van, causing him to land hard on the other side. Supergirl punches one agent in the stomach before throwing a deadly uppercut, knocking the agent a few feet in the air. Felicity grabs her iPad and throws it at the last agent standing, hitting him in the throat.

"Yes!" cheered Felicity.

Green Arrow shoots an arrow into the agent's leg and knocks him out with his bow.

The three speedsters return. Flash stands in front of Smith and gives him the same look that the NSA agent is giving him.

"We just saved the world and this is how you thank us?" questioned Flash.

"You metahumans are more dangerous than any threat we've faced for decades. You're better off in federal custody," said Smith.

"You do realize that killing us wouldn't help you with your case," said Supergirl. "Besides, bullets don't work on me."

"You also gave us more leverage on you," pointed out Green Arrow.

"And now I have recorded footage of NSA agents attacking us," said Atom. "All that's left is to show it to the President and the Vice President."

Supergirl tells Smith, "Maybe it's best you leave us before Dr. Heywood gives you a knuckle sandwich."

Feeling defeated, Smith leaves. All the agents picked themselves up, in spite of their pain and injuries, and leave with Smith. As the heroes watched the vans go away, Citizen Steel and Supergirl smiled at each other, happy to be free of Smith.

It was time for the Legends to go. All that was left were the goodbyes. Barry and Cisco, meanwhile, spoke in private.

"What is it you want you say, Cisco?" asked Barry.

Cisco was silent for a moment, but then said what he wanted to say. "I'm sorry and I forgive you."

"What do you mean?" asked Barry, not understanding.

"I've been so caught up on Caitlin that I forgot something else. We still haven't mend bridges for what happened to my brother," said Cisco.

"I don't need your forgiveness, Cisco," said Barry.

"Maybe not, but I'm giving it to you," said Cisco. "I now know what it's like to screw up something and facing the consequences for it. I went after Caitlin alone, and because of that, I helped her finish her doomsday device and now thousands of people are dead because of me."

"She would've finished it herself," said Barry, trying to tell Cisco that it isn't his fault.

"True, but that doesn't change the fact that I had a hand in Central City's destruction," said Cisco. "I'm gonna have to live with that every day of my life."

"You shouldn't let it consume you," said Barry. "It's not healthy."

"I know," said Cisco. "I just hope you can forgive me for being a jerk. In spite of everything, nothing's changed between us. I am, and will always be, your friend."

While the two best friends hug it out, Oliver and Sara distance themselves from the others to speak privately.

"To think, this all started because of us," said Sara. "Do you ever wonder what it would be like if things went differently?"

"I've already seen it," said Oliver, referring to his time under the influence of the Black Mercy. "It was beautiful, but it wasn't enough."

Oliver and Sara shared a hug.

"Don't I get a hug?"

Everyone was surprised to hear a disguised female voice in the hanger. It was Black Arrow. She removes her hood and mask and reveals her identity.

"Laurel?" Ray was surprised. "Wait, are you a Laurel from another Earth or something?"

"You once trusted Oliver to control the Atom suit like it was a video game," said Laurel, trying to convince him.

Ray smiled, knowing it was the real Laurel.

"So, what are you doing here?" asked Ray.

"To say goodbye to my sister, of course," said Laurel.

Laurel approaches her sister and gives her a big hug. Sara hugged her back.

"Do me a favor. Don't die," said Laurel.

"I was gonna say the same thing to you," said Sara.

After the Lance sisters were finished hugging, Cisco approached Laurel.

"Are you sure you're the real Laurel?" he asked.

"You haven't broken your promise to me, haven't you?" replied Laurel.

"Yup, it's you," said Cisco, remembering the picture he promised Laurel he won't show anyone. "So, uh, is a hug okay?"

Laurel sighs before hugging Cisco.

"Hey, Laurel," called Oliver. "I have the item you requested."

Oliver gives Laurel a duffel bag. She opens it and sees a new suit. It was the same design and made from the same material as Oliver's new suit, only it's black.

"You're still going to fight as the Black Arrow?" asked Thea. "I thought you were considering taking back the Black Canary mantle."

"I was, but I'm not staying," said Laurel.

"What? Why?" asked Felicity. "We still have to stop Prometheus, and having you back on Team Arrow will make us stronger."

"Felicity, I can't stay," said Laurel. "Talia and Chase can control me whenever they want just by simply uttering a couple of words. I have to find a way to cure myself. I'm gonna go find Talia and I'm gonna force her to lift this."

"But Talia is the one who trained you," argued Diggle.

"And Slade was the one who trained Oliver, but look what happened three years ago," said Laurel, sounding confident. "I know this is a dangerous mission, but I can't stay in Star City or I'm just gonna hurt the people closest to me."

Everyone looks at Oliver.

"You're okay of this?" asked Thea.

Oliver nods in response.

"I need you all to make me a promise," said Laurel. "Don't tell dad."

"But why not?" asked Roy. "He misses you. Losing you was the reason he's been drinking in the first place."

"Because, Roy, I don't know if I'm gonna come back from this journey alive," said Laurel. "I don't want dad to worry. It'll just put more pressure on me. Besides, he needs to learn how to be strong on his own."

"Well, consider my lips sealed," said Felicity, pretending to sew her mouth shut.

Laurel raises an eyebrow, feeling skeptical, and looks at Oliver.

"Don't worry. We'll keep her away from Quentin," promised Oliver, referring to Felicity.

"Well, I better get going," said Laurel. "Good luck. All of you."

Laurel gives all of her closest friends a hug. When she approaches Leonard, she gives him the look an overprotective parent would give to his/her child's lover after meeting him/her for the first time.

"Can I trust you to look after my sister?" asked Laurel, sounding like an overprotective parent as well.

"She's safe with me, as I am with her," replied Leonard.

Laurel puts one arm around Leonard, pulling him into a hug, showing him how grateful she feels for him looking after Sara.

The last person Laurel approaches is Oliver. She stares at his eyes for a moment before leaning in for a kiss. Oliver kisses her back. They didn't hold anything back. They kissed with as much passion as they always show when they were dating. Everyone in the room smiled at the sight of this, especially Thea. Laurel had always been her favorite match for her brother and it looks like they might get their happily ever after one day.

After kiss, Laurel says, "Remember. Good, bad, and ugly. Nothing wrong with being all three."

Laurel puts her hood and mask back on as she leaves the hanger.

After the Legends left on the Waverider, it was time for Supergirl to go home. She wanted to stay and be there for Barry, but she has her own crisis on her Earth. Lillian Luthor and Cadmus were still out there on her Earth and she has to stop them.

First, she wanted to spend one more moment with the Scarlet Speedster and the Emerald Archer.

"I'm really gonna miss you guys," said Kara.

"We're gonna miss you, too," said Barry.

"I just wish I didn't have to leave after what happened," said Kara. "I promised to help save this world, but I feel like I failed to keep that promise."

"Believe it or not, you did help us save the world," said Oliver.

"Sure beats screwing up the world," said Barry sadly, hanging his head.

"You are being too hard on yourself," said Kara.

"That's what people usually tell me," said Oliver.

"Well, one things for sure, you two, all of you, you're Earth's finest heroes," said Kara. "Don't ever forget that."

"Now, that's a hard promise to keep," said Barry.

"Barry, I understand that everything that's happened is tougher for you than any of us," said Oliver.

"But hardship is what makes us stronger," said Kara. "That's why the people on this planet look to you as their rock.

Barry lifts his head and smiles. "You guys feeling a group hug?"

"No," said Oliver.

"Oh, c'mon, c'mon," said Kara.

Barry and Kara give Oliver a hug. The former playboy reluctantly and gladly hugged them in return. This was more than just a group hug. The hug was full of trust, compassion, and understanding. The three of them have suffered throughout the recent war, but instead of allowing their broken hearts and broken minds to force them into isolation and depression, they used their pain to fuel their will to continue fighting. They looked up at one another and they stayed together despite hardships and disagreements.

Cisco takes a picture. "One more for the scrapbook."

After the hug, Kara takes out her inter-dimensional extrapolator and opens a breach back to Earth-38. She was about to walk into it, but she stopped. She walks towards Barry and puts a hand on his shoulder in a comforting manner.

"I'm really sorry, Barry," said Kara. "If I could fly fast enough to travel back in time, I would save her."

"As nice as that sounds, doing that comes with consequences," said Barry.

The two just laughed together. The longer Kara looked at Barry in his eyes, the more she wants to put her lips on his, but she controlled herself, remembering that he's still mourning for Iris and she was not gonna steal him away from her even if she's gone.

Kara walks away towards the breach, but Barry quickly pulls her back and crashes his lips onto hers. Kara was about to pull away, but she didn't. She just rubbed the back on Barry's hair as she kissed back.

Wally and Jesse reacted with shocked, surprised, and proud looks. Cecile and Team Arrow smiled. Joe and Cisco just raised their eyebrows.

After the kiss, they looked into one another's eyes again.

"Why did you do that?" asked Kara.

"Because it's what you want," answered Barry.

"Barry Allen. Always thinking of others," complimented Kara with a smile.

Barry smiled back.

Kara was beginning to walk towards the breach, but she was still holding Barry's hand. The two didn't want to let go of each other, but they knew they have to. Kara enters the breach as she lets go of Barry's hand. The breach closed. Barry was sad that she had to go, but he knew that he was gonna see her again someday.

"Okay, what the hell was that?" asked Cisco, confused and shocked.

Everyone glares at Cisco.

"I just ruined what's supposed to be a dramatic goodbye scene, didn't I?" guessed Cisco.

Wally and Jesse nodded "yes". Feeling awkward, Cisco walks away.


At the D.E.O., James, Alex, Winn, J'onn, and Mon-El were tracking down an alien fugitive on the loose. Suddenly, a breach opened. Coming out of it was Supergirl.

What Kara didn't expect to see was her sister Alex, alive and well. Kara was frozen, feeling a mixture of shock and happiness. She runs towards her sister. Alex did the same. The two sisters hugged like they haven't seen each other in a long time. Kara started to cry tears of joy.

"I thought you were dead," said Kara.

"And I thought you were gonna be dead," said Alex.

"How are you alive?" asked Kara.

"She only pretended to kill me," said Alex. "She wanted to make you suffer."

Kara hugged Alex again, overfilled with joy seeing her alive. However, her bone-crushing hug was doing as it was described.

"Ow, Kara, ow," reacted Alex.

"Sorry. Sorry," apologized Kara, letting her go.

"Hey, c'mon, what am I? Mushroom in the corner?" complained Winn, feeling left out.

Kara then proceeds giving Winn and the rest of her friends a hug.

"So, how did everything go on the other side?" asked Winn, referring to Earth-1.

"It was... I don't really want to talk about it," said Kara. "It's too painful."

"Well, you're home and that's what matters," said Alex.

"So, uh, apple pie at my place?" offered Kara.

"No!" said everyone, stepping back.

"I'm still trying to get the hang of this whole baking thing," said Kara.

"More like grief-baking," said Alex.


For the first time in a week, Barry returned to the West household. It was half-damaged, but it was still standing. He found a family picture on the floor and picks it up. It was a picture of him with Joe, Wally, and Iris. Once again, the thought of Iris brings him nothing but sorrow because she's gone. He can longer hold her in his arms. He can no longer ask for her comfort when he's feeling down. He can never have the future he wanted with her. Once again, he pins the blame on himself.

Barry sits down on the couch as he looked at the picture. All he could think about is what has happened for the past few months.

"Well, that's what happened. Caitlin, my best friend, someone I trusted, someone I loved, destroyed my city and killed the woman I love. She said she wanted to make me pay for my sins, and it seems I paid my debt with thousands of innocent lives, including Iris. I have faced so many dangerous enemies since I became the Flash, but Killer Frost was, without a doubt, my greatest enemy. She didn't just know how to overpower me. She knew me. She knows how I think, how I act, and who I care about. She used my emotions and the people I love against me. She did what none of my enemies ever did. She broke me. I felt a lot of emotions about what she's done. Anger. Desperation. Sorrow. But she actually pushed me so far that I didn't even want to fight anymore. In fact, I don't if I can go on. It's over. Caitlin's gone. Iris is gone. S.T.A.R. Labs is gone. What point is there?"

Barry puts the picture aside as he breaks into tears once again. The emotional wounds he tried so hard to ignore reopen. There was absolutely nothing for him to be happy about. He failed to protect his city. Iris is dead. He lost Caitlin just as she was beginning to become herself again. A part of him wanted to travel back in time and undo his mistakes, but after what happened with Flashpoint, he knows he can't risk it. He has to live with the consequences of his actions. However, he is unsure if he's able to live at all.

Hub City (Three Months Later)

A masked man named Charles Victor Szasz was walking down the streets in the middle of the night. He ignores a nearby dog fight and some teenagers fighting next to a car as he proceeded to where he needed to be. He turns a corner arrives at Ubi Street. He turns his head to an alley and found someone standing in the shadows. He walks towards the figure in the dark.

"Well, here I am," said Charles. "If you don't mind, I like to look at my informants in the eye when we speak."

"If you wish," said the person in the shadows.

The mysterious figure comes out of the shadows and reveals herself. She is a woman who looks to be in her 20s, has long dark brown locks with a few strands colored as white as snow, and wearing clothes with different shades of blue.

"Do I know you from somewhere?" asked Charles, scratching his chin.

"I get that a lot," shrugged the woman. "So, the folks weren't lying. An investigative reporter who wears a mask to appear as if he has no face at all."

"So, you said that you have some intel on Able Crown?" asked Charles.

"Indeed, I do," said the woman.

The girl takes out a file and gives it to Charles. Charles opens it and sees the picture. He recognized the man as Able Crown. He quickly glossed at some of the most significant facts on the file. Some of the information seemed to be too personal. It makes him wonder how anyone could get their hands on it.

"I assume you're satisfied?" asked the woman.

"The question is, 'How did you manage to stumble upon all this?'" said Charles.

"Should it matter?" asked the woman. "Now, you have enough dirt to put Crown behind bars for life. Justice is served."

"In my experience, no one digs this deep into someone unless it's personal," said Charles. "The question is, 'What did Able Crown do to you?'"

"It may be personal, but I like to keep my reasons to myself," said the woman.

"You're the mysterious kind. I am intrigued," said Charles. "The question is 'Who are you?'"

"You ask way too many questions," said the woman. "If you're thinking of a nickname to go with that face, try 'The Question'."

Charles laughs a little. "I guess I'll leave you to your business, miss..."

"Frost. Crystal Frost," said the woman, introducing herself.

"Well, have a good evening, Ms. Frost," said Charles.

Charles left the alley and returned home, waiting to bust Crown in the morning. Crystal, meanwhile, watched him walk away. If his mask wasn't what intrigued her the most about him, it was his job. Why would an investigative journalist accept intel from strangers such as herself?

"I'm sure the Green Arrow would love to meet him," she muttered to herself.


Well, that's the end of the story. It has been a wild ride. I know I've said this before, but I'll say it again. I loved writing this. It's nice to know that a lot of readers seem impressed by it. It makes writing this feel worth it.

I'd like to announce that I'm planning on writing spin-offs and a sequel to this story. I like to call this my "Unforgivable" series. There will be one spin-off for each show in the Arrowverse. One will be posted on the Flash archive. One for the Arrow archive. One for the Supergirl archive. One for the Legends of Tomorrow archive. I'm still waiting for the end of Flash S3, Arrow S5, and Supergirl S2. As for the sequel, I'm waiting until after the very first Justice League movie because, to be honest, I could use some inspiration.

Good day to you all.
