Grey's Anatomy Season 8 Episode 8

Lexie: Hey, you paged? I can't get out of here yet, I gotta follow up with my patient and make sure she's in the right frame of mind. ... You okay?
Jackson: Yeah. I-I just missed a surgery today. Th-That's not true. I avoided a surgery today, one that I wanted to do for weeks because of this thing with you and Mark.
Lexie: There is nothing between me and Mark.
Jackson: Yeah, I've been trying really, really hard to believe that. But there is a thing and it's not going anywhere anytime soon. And this new thing with me and plastics, that's not going away either. Something's gotta budge. So, I have to walk away from you, for me.
Lexie: So... You're picking Mark.
Jackson: I've spent way too much time sabotagging my own career, Lex. So, yeah, I'm picking Mark. ... Can you-- Can you tell me that I shouldn't? (Lexie is silent, Jackson nods and walks out)
