And the Line of the Episode goes to - Meredith (Ellen Pompeo) for telling Derek (Patrick Dempsey), "McDreamy is being a McAss!" Fortunately or otherwise, it turns out to be but a momentary glitch in the domestic / marital bliss that the two's been enjoying. Side note: does Meredith openly call Derek 'McDreamy' to his face? On this episode of Grey's Anatomy, Izzie (Katherine Heigl) will be back. And the fact that her hubby (Justin Chambers) just slept with Lexie (Chyler Leigh) makes things a bit more complicated. Thankfully, the only person who knows - Meredith - is willing to shut her mouth for the mean time, the same thing she wants Derek to do when he found out about the Chief's (James Pickens, Jr.) drinking problem. She invokes the grounds of their post-it wedding to win the argument. Also, we'll get to see the aftermath of Cristina (Sandra Oh) telling Teddy (Kim Raver) that, essentially, she's willing to trade Owen (Kevin McKidd) off just so she'd stay. Now she tells her that she didn't mean it, but Teddy's not too convinced. Source & Preview
