"I love you," Kurt Hummel told his boyfriend Blaine Anderson as they sat on the living room couch in Kurt's house. Kurt had his head on Blaine's lap and Blaine was combing Kurt's hair through his fingers as they watched a movie.

"I love you too," Blaine replied simply, looking down into the happy, smiling face of his boyfriend.

Kurt sat up and pressed his lips to Blaine's. Blaine reciprocated enthusiastically and wrapped his arms around Kurt's waist, pulling him closer. Before things could get any deeper, however, they were interrupted by a voice at the door.

"Oh god, guys." The boys pulled apart at once to see Finn standing in the doorway, a grossed out expression on his face. "I know you're all in love and stuff, but can you not do it in the living room? It's a communal area."

"Where'd you learn that word?" Kurt asked curiously as the blush faded from his cheeks. The word was obviously not one usually in Finn's vocabulary.

"Rachel," Finn said proudly. "She taught me that one yesterday. But that's not the point. No offence, but I don't want to see that in my own living room. I mean, you're my brother."

"Well we're sorry that you happened to walk in on us, Finn, but nobody was supposed to be home. And I happen to know for a fact that you and Rachel do just as much, if not more right here when you think we're not home. Why are you here, anyway?"

"Puck had to drive his little sister to the hospital. She fell out of a tree and broke her arm. Halo day was cancelled."

"Is she all right?" Blaine asked.

Finn just shrugged.

"Well, I'd better be going, anyway," Blaine said, pulling Kurt off of him. "I told my mom that I'd be home for dinner."

"Don't leave," Kurt pouted. "Stay with me."

"I wish I could. I'll see you later."

"Are you coming over tomorrow?"

"I can't, I've got plans."

"Oh? What?"

"I'm hanging out with someone."

"Who?" Kurt asked curiously. By now he had met almost all of Blaine's friends.

"Just an old friend," Blaine replied vaguely, and Kurt decided to let it drop. If Blaine didn't want to share than that was his business.

Kurt nodded. "Okay. Call me when you get home."

"I will. Love you."

"Love you too."

With one last peck, Blaine was gone and Finn was staring at the boys with a mixture of disgust and amusement on his face.

"You guys are disgusting, you know that?"

Kurt just rolled his eyes.

The next day, Kurt made plans to go out with Mercedes. When he arrived at her house to pick her up however, Santana was there too, which wasn't surprising.

Santana and Mercedes had an odd sort of friendship. After their River Deep Mountain High duet, they became friends—sort of. They were terrible to each other all the time, but the malice had gone out and it was now mostly joking.

"Santana?" Kurt asked, "What are you doing here?"

"Satan here invited herself to come along on our outing," Mercedes rolled her eyes, but grinned.

"Hey—I keep it real," Santana said, flipping her long, black hair over her shoulder. "You know you love me."

Kurt copied Mercedes and rolled his eyes at the Latina. "Whatever, let's go. We're going to the mall in Westerville."

"Any particular reason you chose Westerville?" Mercedes asked suspiciously as they made their way to Kurt's car. "You'd better not have planned for your warbler to meet up with us. This is a girl's day."

"No," Kurt shook his head, climbing into the drivers' seat and starting the car. "Blaine said he has plans with an old friend today. I chose the Westerville mall because it has a better selection than the Lima one."

"All right, but if I find out you're lying to me, I'mma have to hurt, you, boy."

Kurt just laughed.

"How's your man, anyway, Hummel?" Santana asked.

"He's good," Kurt smiled. "He's working at the six flags this summer, so I don't see him as often as I would like, but he has this week and next week off, so we're spending as much time together as possible. How about you? Are you still with Karofsky?" Kurt grimaced inwardly at that statement, solely because he knew what was going on with the two.

"I'm trying to get over someone," Santana said simply.

"Brittany?" Mercedes asked.

"No; Zizes," Santana replied sarcastically. "Of course it's Brit."

During the summer, Santana and Mercedes had been spending every day together. Santana didn't have as good of a home life as she liked everyone to believe, and took refuge in Mercedes this summer. Soon enough the two had shared most of their secrets and Santana had become one of Mercedes' best friends, much to the confusion of everyone else. So naturally, Mercedes knew all about Santana's Brittany problems. Kurt knew too, because of the information he had on Karofsky and his excellent gaydar.

The conversation soon moved away from Santana's problems and before they knew it, they had arrived in the mall parking lot.

After trying on countless things, and spending way too much money for their own good, the girls and Kurt headed to the food court for lunch.

"Hey," Mercedes said as they sat down at a table, "Isn't that Blaine? Did you lie to me?"

Kurt looked over and sure enough, saw the overly gelled hair that was Blaine Anderson's. "I didn't know he'd be here. He must be meeting his friend here."

They all looked over to where Blaine was deep in conversation with the boy, who had long, dark hair and wore square glasses. Blaine reached over and took the boy's hand and said something very seriously. The boy nodded, smiled and then—Kurt gasped loudly—hugged Blaine. Blaine returned the hug, smiling. They stayed in the embrace longer than necessary and Kurt knew that this wasn't a platonic friend hug.

Both Mercedes and Santana gasped as Kurt turned away front he scene, disgusted and his eyes slowly starting to fill. Mercedes and Santana were speechless, staring at Kurt with their mouths wide open.

"Close your mouths," he snapped, wiping the tears from his eyes with a napkin before they spilled over. "You'll let flies in."

The girls obeyed and they three sat in silence before Mercedes said, "Oh HELL to the no. If he's doing what I THINK he's doing, that boy is in for a beating!"

"I'll help!" Santana said angrily. "I'm from Lima Heights Adjacent. That's the wrong side of town to be messing with. I'mma go all Lima Heights on that hobbit's scrawny ass for cheating on you."

"Calm down," Kurt said slowly, trying to process all the information. "We don't know for sure. Blaine's very touchy feely. Maybe they really ARE just friends."

"That was a pretty lingering hug," Mercedes said softly. "More than a 'just friendship' hug."

"It could be, though," Kurt replied stubbornley. "We can't form any sound conclusions before getting more evidence. But I agree that it's fishy. Would you two like to help me spy and figure out what's going on?"

"And if what we find out is bad?"

"Then I'll—I'll break up with him," Kurt replied, choking the last four words.

"Oh, Babe," Mercedes said, pulling her friend into a hug. "It'll be all right. We'll get evidence and confront that cheating little—"

"Can we not say that word please?" Kurt interrupted. " At least until we know for sure that he's actually doing it."

"What, cheating?"

Kurt just nodded. "And can we keep this quiet for now. I promise we'll tell the others. Just not yet." He didn't want to listen to all the other girls' sympathies and the boys' threats to beat him to a pulp.

Both girls agreed.

"Well," Santana said. "I'm perfect for this task. You see, I'm an expert on cheaters, being one myself. I could tell that Quinn was cheating on Sam with Finn because of one look! You'll be glad to have me for this." She grinned mischievously.

"How could you tell from just one look?" Kurt asked, momentarily forgetting his distress.

"Quinn was wearing her queen-bitch smirk while Finn had his gassy infant look. The queen-bitch smirk is when Quinn is being even more of a bitch than usual and may have done something particularly bad, while Finn's gassy infant look means he's feeling guilty."

"So you gave them both mono to prove it and everything was ruined thanks to your truth telling." Mercedes finished, rolling her eyes dramatically.

"Anyway," Santana said. "This just means that I can help you discover the truth."

"All right," Kurt nodded. "Operation Find out if Blaine is cheating is a go!"
