Meredith and Mark stood alone in the elevator.
"Ok, before you start, there are rules to this friendship thing or whatever," she told him.
"The Dirty Mistresses Club has rules?" Mark asked in disbelief. "Gosh, I thought a bunch of dirty mistresses would be a little less uptight about these uh, rules."
Meredith turned and glared at him. "Number one, no flirting. Second, no talking about Derek and C, no giving me the face."
Mark looked at her. "The face?"
"The McSteamy face," she said dismissively. "Doesn't work on me. I'm immune."
Mark leant in closer to her. "You know, if I'd gone off to the woods, I would've invited you to keep me warm."
"Breaking rules one, two and three!" Meredith protested, pulling away.
Mark laughed.
