Chapter 1 Secrets Kept and Known

The MacDonald-Venturi house was one of constant chaos. Mainly because of the eldest two step-siblings, Casey and Derek. This day was an exception to the rule. Derek and Sam were downstairs playing video games and Casey was in her room doing homework, so they were no where near each other. Derek had just broken up with Kendra, so everyone was being expecially nice to him.

That evening Sam was invited to stay for dinner and gladly accepted. Everyone was trying to cheer Derek up, even though he said he was fine. Some how the conversation turned to everyone's old relationships and George decided to bring up an old one of Derek's girlfriends. "Do you remember that girl you used to date? It was before I married Nora."

Derek looked panicked. "Dad."

"I remember her," Sam chimed in. "Derek never would introduce anyone to her. He dated her for an entire month and never even told me her name."

"Sam."

The George came back in. "I kept asking about her, but he never would tell me anything. Then one day he came home and said they had broken up and for about two weeks he moped around here and didn't go anywhere. He even missed a hockey game."

"Dad, seriously, cut it out."

Edwin was staring at his brother. "How long has it been since she broke up with you, Derek?"

Derek looked at Edwin, then to his watch, then back to Edwin. "Two years, five months, one week, three days, five hours, and forty-six minutes." He looked around the table and saw everyone staring at him. "Excuse me." He got up and climbed the stairs.

As soon as he disappeared Nora began glaring at her husband. He got defensive. "I didn't know he still felt that way, honest, otherwise I wouldn't have said anything. I knew he really liked her and I was trying to remind him that it was possible to get over Kendra. I didn't know he wasn't actually over that girl."

Twenty minutes later Sam had gone home and Casey was heading up to her room while the rest of the family cleaned the kitchen. She looked at Derek's door and paused. She glanced behind her then leaned against the door to hear the music that was playing. It was a recording. One she had a copy of. She carefully opened the door and slipped inside Derek's room. Closing the door behind her, he still hadn't noticed her, since he was sitting with his back to her. "Forty-seven," she said, barely above a whisper, but he heard her anyway.

He whipped around in his chair and stared at her. "What?"

"It was forty-seven minutes, not forty-six. Only by two seconds, but still."

"Only because it took a few seconds to get through the rest of it."

They stared at each other in silence for a few moments. "How often do you listen to that song?"

He shook his head. "Not very. Normally I just play, though it's in past tense when I do."

She nodded. "I can understand that."

"Are you really as excited as you claim for university?" It was barely a whisper and Casey could hear the pain in his voice.

She nodded. "Yes."

"Why?" He had tears in his eyes, the same as her.

"Because maybe there I can finally stop being mad at my mother."

"Why are you mad at her?"

She sat down on his bed and let a few tears fall. "Because if she hadn't married your dad I know we would have gotten back together and we would have been together forever." She put her face in her hands and started sobbing.

Derek sat watching her for a moment before deciding that he didn't have to be a cold-hearted bastard in the privacy of his own room. He sat down next to her and pulled her head to his chest. He felt the same way. Even though he had messed up badly, they would have worked it out. They loved each other more than anything in the world and there would have been nothing to keep them apart if it weren't for his dad marrying her mom.

As he stroked her hair an air of familiarity consumed them. "Do you think there is chance for us anyway?"

She stayed against him, but he could tell she was stiff. "I don't know, Derek. I don't think so." She sat up and looked at me. "I mean, how could we really be together. It would be so weird for the family and I don't want to do that to them."

Derek stood and walked to the other side of his room. "But it's already weird between us."

"That's different."

"How? You think they don't notice how we act towards each other? Casey, they know as well as we do that their hopes of us acting like siblings is a pipe dream."

"It's different because we can hide it. We can cover it up. And it's only the two of us."

"So you would rather both of us go through life miserable than cause a little discomfort for our family. They would get over it eventually, Case."

Casey shook her head. "Derek..."

He turned around and looked at her with a sadness in his eyes that she had only seen on the day she broke up with him. "You are the only girl I have ever and will ever love, Casey. But if you don't think we will work anymore then I'll stay away. I'll act like an asshole and ignore you whenever possible."

Casey's eyes filled with tears. "Derek..."

"Just go, Casey. You know how I feel when I'm alone with you."

Her chin quivered, but she nodded and left his room. When she had closed the door to her own room she leaned against it and slid down to the floor. Then she let her tears flow. She looked at the wall that separated hers and Derek's room. "I love you so much," she whispered.

In the room next to her Derek was having a similar melt down. He leaned his head against the wall and let the tears stream down his cheeks. "I'll leave you alone, baby, I promise."

A few weeks later...

Casey was sitting at her desk when Lizzie came into the room. She sat on her sister's bed and watched as Casey smiled at her in the mirror, told her to hang on a second, and typed another few lines. Then Casey spun her chair around to face her sister. "What's up, kid?"

"I'm worried."

"About what?"

"You and Derek."

"What about me and Derek?"

Lizzie could tell that Casey didn't want to be talking about Derek, but she had to get the truth out of her. "Casey, ever since dinner a few weeks ago, when George mentioned that one girlfriend that Derek hasn't gotten over, I've been thinking." She looked up to gauge Casey's reaction to what she was saying, but there wasn't much of one. "I was thinking about that boyfriend you had that you never let, even me, meet." Now Casey was looking at the floor. "And I know that you her really in love with him and all and I realized that you were dating him at the same time that Derek was dating that girl. Then I started noticing that you both seemed kind of depressed since then and that you two are never in the same room for very long." Lizzie paused to take a deep breath before asking the question she already knew the answer to. "You and Derek dated, didn't you?"

Casey stared at her sister, shocked that she had figured it out. She just nodded. She knew she was a horrible liar and Lizzie knew her best.

Lizzie smiled. "Why don't you two get back together?"

"Well, because we don't want things to be weird for everyone else around here."

Lizzie shook her head. "I don't think it would be weird. And ever since you and Sam broke up for good, Marti has been saying that she wants you and Derek to get married." Lizzie looked thoughtful for a moment. "In all honesty, I think Edwin knew already that you two had dated. I don't really know why I think that, I just have had this feeling for a while that he knew something I didn't and he just couldn't tell me. I didn't realize until this past week that the secret was with you two."

Casey smiled. "Well, I don't know. I will never rule out getting back with Derek as a possibility, but it isn't very likely."

Lizzie nodded. "You know I just want you to be happy, right?"

Casey nodded and pulled her sister into a hug. "I know, thanks."

At the same time as Lizzie walked out of Casey's room, Edwin walked into Derek's. When he entered the room he immediatly slammed the door. "Dude, we need to talk."

Derek's head snapped up and glared at his younger brother. "Ed, what are you doing? Get out."

Edwin shook his head and crossed his arms. "I need to talk to you about Casey."

Edwin saw Derek's eyes change, though he couldn't decide if they were harder or softer than before. "Why would I want to talk about Casey? Better question, why would I know enough about Casey for you talk to me about her?"

"It's not about what you know about her, it's about what I know about her. And what I know about you."

Derek crossed his arms and waited for Edwin to go on.

"I know that you and she dated before Dad married Nora."

Derek just stared at him, though Edwin could see the shock in his face, even if it was subtle.

"I got home early one day from school and you brought Casey over. I didn't say anything because I knew were trying to keep it a secret for a while and I didn't see any reason to change how things were going. I wanted to tell you that I think Lizzie figured it out and I know she was just talking to Casey. Neither of us would have any kind of problem with you guys getting back together."

"Ed, it wasn't my idea that we stay apart. I've been wanting to get back together with her since she broke up with me, but Casey doesn't want things to be weird around here. I have to respect that, Ed. If Casey decides to get back with me, I will have no objections and will agree in a heartbeat, but I can't force Casey."

Edwin nodded. "If you still love her, then why do you avoid her so much, especially lately?"

"Because if I don't avoid her, I'm going to kiss her."

Edwin nodded again. "Just so you know, Marti wants you and Casey to get married."

With that Edwin left. Derek stared at the door waited for his mind to clear. He wanted to go strait to Casey's room and talk to her about this, but he knew that there would be no way she would talk to him about this again. He put his face in his hands. "It doesn't matter if your siblings are cool with it, Derek, it's over. Casey said it's over."
