Lexie Grey breezes up to Mark Sloan who is looking at the schedule and says, “hi.”  “What are you doing,” Mark asks.  “I’m saying hello” she tells him casually.  “Look,” Mark begins, “my best friend made one simple request – that I not get anywhere near you and I slipped.  It was fantastic and you were fantastic, but it’s not going to happen again. Ever.”  Lexie agrees, unconcerned, and walks away.

In the mean time, George O'Malley is in with a patient who has a broken leg.  The patient is completely beside herself.  This is the sixth break in two years.  George decides to run some more tests this time to see what is really going on.

Callie Torres gets involved and tells Sloan that they’ve got a parathyroid tumor to remove.  No sooner are the words out of her mouth than Lexie is walking by and overhears.  She eagerly asks to get in on the surgery.  Callie quickly agrees before Mark is able to refuse her.  “Fine, but you’re not touching anything.  No touching,” he tells her.  That one’s not getting past Callie.  She knows right away that Mark’s slept with her  and as soon as Lexie leaves she teases him about it.  “It’s like I had no control, she violated me with her nakedness,” he explains.  She laughs at him, but the two soon get interrupted by Sadie Harris.  Sadie reaches over to Callie’s ear and gently works a piece of lint out of Callie’s hair as she delivers the labs to Callie.  Fumbling over her words terribly, she sends Sadie to Lexie and George for the update.  “I’m telling you, these interns are out of control,” says Sloan.  “Stalkers,” Callie adds.  “Sex stalkers,” Mark finishes.  

The group of doctors and interns go in to tell the patient about her tumor in her throat.  The patient is, again, beside herself that she can have such lousy luck.  They explain that it’s actually good news, it’s easily removed, it’s benign and she’ll be back to normal, but he patient is still upset.  The patient explains that she’s been living “like an old lady” because she didn’t want to hurt herself.  She goes on to say how she fell in love with a guy who moved to Denver and she didn’t because she was worried she’d slip on the ice.  She lost her man and gave up so much of her life because of a tumor and she’s frustrated.

Mark and Callie are in an on-call room trying to figure out how they’re going to keep their minds off of the hot interns who plague them.  Slkoan admits that it wasn’t’ just the sex, they talked for hours afterward and he enjoyed her.  Callie admits that she’s a fraid to have any more romances in the hospital because eshe’s had so many go bad that it’s embarrassing.  They even try to have sex to make it right, but it’s not happening this time.  Callie decides that they are like addicts and they need a 12-step program to get off interns.  She starts to make up the rules, “Don’t get naked with interns, (pause) it’s more like a one step program.”  

Before surgery, Callie and Mark give each other a pep talk about how they aren’t going to fall for the pretty interns tricks.  After the successful surgery, they go in to the patient to discuss.  It went well and she’s now ready to go to Denver to try to get her man back.
