According to some rumors, Grey's Anatomy will open 2010 with a bang, quite literally, as apart from the crossover with Private Practice, there won't be one but two hook-ups between unexpected people as the second half of this season kick off.
Of course, we already know that Karev (Justin Chambers) will have a little something on the side while Iz (Katherine Heigl) is still away. Chambers said so himself, and opined that it will surely "add spice" to Grey's Anatomy.
"I was totally thrown off by it. I think it's great though... The writers are really good at turning corners and taking your head for a little spin. It surprised me as much as it will the audience."
So who is the mystery girl? Judging from the polls and online guessing games, a lot of Grey's Anatomy fans seem convinced that it's indeed Mercy Wester Reed with whom Alex will be fooling off with. Others, meanwhile, cite a leaked spoiler that it's Lexie (Chyler Leigh), and the two will do it while Sloan (Eric Dane) is busy doing the nasty with Addison (Kate Welch) - obviously, it gets really crazy here.
At least TV Guide has able to take some names off our suspect list, and with the revelation of a love interest for Bailey (Chandra Wilson), she's also out of contention. TV Guide says it's not Meredith (Ellen Pompeo) and it's not Callie (Sara Ramirez) or Arizona (Jessica Capshaw). So that leaves it to Reed, Lexie, Yang (not likely), and McSteamy's daughter (who is sick, so it's also not likely).
"Callie and Arizona get a little sexy soon," Capshaw has previously revealed. "We see a little girl-on-girl action. America was asking for it and America got it."
