Elliot knocked on her door. He knew she was home. She never left her light on when she wasn't.

"Liv, I know you are in there," he knocked again, "Open up."

The door flung open with alarming force, "Are you trying to wake up all the neighbors? Or my son for that matter?"

"A little birdie told me he was at a sleepover this weekend," Elliot smirked.

"Okay well you are still going to wake up the neighbors," she rolled her eyes, knowing exactly who snitched on her. She stepped aside and let him in. "What do you want?"

"I wanted to talk to you."

"Yeah, I got that from the many, MANY, missed calls," she crossed her arms.

"You're mad at me. I get that," he looked at the ground.

"El, I'm not mad at you," she sighed, "I'm just having a hard time. I didn't know if I would ever see you again, and I had to come to terms with that. In my own way."

"I should have called."

"You should have…" she paused, looking for the right words, "done something! I mean even a note or anything."

Elliot looked at her with frustration in his eyes, "And what exactly should the note have said, Liv? What could I have said that would make thing okay? You know why I left. You didn't need a note to tell you that." He voice was increasing in volume.

"How the hell was I supposed to know why you left?" she looked at him with anger now.

His lack of words told him everything she needed to know.

"Kathy," she breathed, "She made you leave."

Elliot suddenly got slightly defensive of his late wife, "She didn't make me do anything." Olivia took a small step back at his anger. Elliot sighed, "But she asked me to make a choice. And I chose my family."

"You made your choice," Olivia wasn't sure how to take this. She knew Cathy was jealous of her in some ways, but she never thought she would ask him to choose.

His voice was barely above a whisper, "It was the wrong one."

Her head jerked up, not expecting that response. Their eyes met and anger rose up inside her, "Are you kidding me? You show up here after all these years to tell me you made the wrong choice? Do you think that makes a difference? Do you think I'm just going to forgive you and be best friends like nothing happened?"

Elliot was over to her in two quick steps. He pushed her up against the wall and put his hand in her hair, his face inches from hers, "Do you really think I was to be your friend?"

Her breath caught in her throat, "El, I –"

Before she could say more, his mouth was on hers. He kissed her with the passion he had been holding in and trying to suppress. He pushed into her, his hand grabbing onto her hair. Just as she reached to pull him closer, Elliot's phone went off.

He broke away from her, his face flushed. He looked down at his phone and awkwardly said, "I'm sorry. I have to go."

The door closed behind him, and Olivia stood there wondering what the hell just happened.
