Ghost? How is he a ghost? He's not a ghost. A ghost would be if she saw him standing there... he's an after-person. Someone did die. Meredith did. But people have died and come back to live... Only takes a few seconds, but it has happened. The thing about Shonda Rimes is, the woman has balls. She could go there, and I belive, survive it. She's not afraid to break television rules. I'm actually not reading spoilers, but I think either Ellis or McDreamy will really DIE-DIE but Meredith will DIE-LIVE. I love George and Callie together, but I get Izzie's rant about it. She's terrified of losing her best friend. She belives he's made a mistake because in her mind, Callie's not right for George, she's not good enough for him (in that "no-one's-gonna-be-good-enough-for-your-best-friend" kinda way).
