"Grey's" is back! What more is there to say? After way too long a break, "Grey's Anatomy" finally returns tonight at 9 p.m. on ABC. (If you need a refresher, check out my recap of the season so far.) Judging from the promo below, it looks like there's some cuteness with Meredith and Derek and some serious drama with George. But who can even concentrate on that when there's a shot of Alex and Addison (almost) kissing?
