When it comes to TV, rumors often turn out to be true. Word was that Katherine Heigl and T.R. Knight were preparing to leave "Grey's Anatomy." And at the end of last night's season finale, both Izzy Stevens and George O'Malley appeared to be gone: Izzy crashing, cancer-stricken, in her hospital bed, George coding in an operating room after being hit by a bus.
In both cases, no one called a time of death; there's room for resurrection and contract negotiation, not necessarily in that order. But in truth, it wouldn't be so bad for "Grey's" to lose these two, instead of straining to squeeze them into yet another season. Their characters have taken so many twists and turns that, at some points, they've become unrecognizable.
