First of all, no way is Meredith dead! She is the title character, there can be no "Grey's Anatomy" without a Grey, and her mother is not lucid enough to come back to Seatle Grace. I must admit I was happily surprised when Denny appeared at the very end. I love the idea of having some more Denny, I have missed him and didn't think we'd see him again on the show. The writers are brilliant: Meredith has a near-death experience and gets Denny as her guide. Can you say "Sweeps"?
I was ready to jump up and smack the TV when George announces that he's going to "kiss Callie silly" at home. Hello, she's in surgery. He doesn't know the boy's condition. Can you say "inappropriate"?
