You can't kill off the character that the show is named for! So I wasn't really in a lot of suspense waiting to see if she would live or not.
I thought it was an interesting episode. Kinda cool how they did the afterlife thing. I'm glad Mer did get some positive closure on her relationship with her mother. And I do feel bad for Richard.
Izzy needs to snap out of whatever trip she is on about George and Callie. She's being a total witch. You just don't tell friends that they made a mistake getting married. Personally, I think that she's jealous, and is being very selfish. It's like no one else should be allowed to be in love and get married because she wasn't able to marry Denny.
