Mere walks down the hall and when she opens the door and tells Alex about Izzie, sees that her sister is there in bed too, and both are very without clothes. Once they're all dressed they meet up in the kitchen where Mere berates them for falling into bed when shit got hard with their significant others. Alex rightfully points out that she can neither judge nor give relationship advice and calls her out on being a dirty mistress herself just recently, but she points out that it was two years previously and that the wife didn't have cancer. Lexie freaks out about now being a dirty mistress herself, but defends that it's no big deal as they have slept together before. After some more arguing, Lexie panics at the thought that Mere will tell Derek and he'll tell Mark, but Meredith vows that no one is telling anyone anything because no one needs to know. This was obviously Izzie's clue to walk in, though she didn't actually hear what went on, so she just asks with a sharp edge to her voice what they're talking about. I know I don't give her much but I'll be fair and give her this -- her shoulder-length, curly blonde hair and her makeup both look phenomenal. She's a bitch, but she's a good-looking one.
