Izzy and George?

It seems that March Madness applies not only to basketball, but also to the shenanigans at Seattle Grace Hospital, because now it appears that, despite having consumed an entire bottle of booze, Izzie and George DID have sex (more than once!) and now Izzie thinks their hook-up was "God's plan" or something, because it was so very, very right, even though those of us who've been playing along at home have never seen any evidence of sexual chemistry between the two of them ever. After a lot of hangover-induced guilt from George and weird behavior from Izzie and a very poorly timed visit from Callie's dad, Hector Elizondo, George tells Izzie that he can't tell Callie about their rendezvous because it wouldn't be fair to hurt Callie just to ease his conscience. Izzie reluctantly agrees, but does a lot of crying, because…she's in love with George? If you say so. whatevs.
