I'm letting you go, but you have to walk away.

Lexie: You have to stop. You gotta stop talking to me and checking on me and talking to my boyfriend. I love you, and I'm always gonna love you, but I don't want to love you. I want to be happy, and Jackson makes me happy. And if you keep pulling at me, I'll come back to you.

Mark: You're right, I'm sorry.

Lexie: You got what you wanted, you wanted a family so please just let me have what I wanted.

Mark: I said you're right. I told Avery I was letting you go. Did he tell you that part?

Lexie: Yes, it's paternalistic and weird.

Mark: I'm letting you go, Lexie. That means you've got to walk away.

Lexie felt defeated when she heard Mark telling her to walk away. In some twisted world, she thought that he would carry on fighting for her despite all of her dismissals until he actually got her. She just told him that she would come back to him if he kept pulling at her and yet he decided to let go. She didn't want to walk away. She was happy with Jackson but it wasn't enough, it was just a temporary fix. But Mark had a family and that was something Lexie wasn't ready for. So she turned and walked away. She took a couple of slow steps in the opposite direction of Mark but stopped and looked back to see if Mark was still there. He was watching her and when she turned back, their eyes met. Suddenly Lexie turned back around and ran to Mark, kissing him passionately. She pulled out as she realised they were somewhere where they could easily be seen.

"Let's go somewhere private." She suggested.

Before Mark could question her motives, Lexie held his hand and led him to an on-call room. As soon as they went inside, she wasted no time and ripped her scrub top off and then the vest she was wearing underneath so she was just in her bra and scrub bottoms. Mark was having deja-vu but he didn't question it. Not right now. He proceeded to take his scrubs off and picked Lexie up and dropped her onto the bed so he could take her pants off. Then he climbed on top of her. Lexie took Mark's face into her hands and kissed Mark as she wrapped her legs around his waist. Mark then made his way down Lexie's neck with a trail of kisses until he reached her breasts. She arched her back so he could unclip her bra but as he did, the door of the on-call room opened.

"Oh my God! I-I I'm so sorry!" It was a nervous and red-faced April Kepner, the best friend of Jackson Avery.
