I've been going CRAZY trying to remember what episode a particular quote comes from; I think Blanche is talking to George (and I'm pretty sure he's not actually in the scene, but I could be wrong), and she goes "Promise me you won't ever die" (or something along those lines, I REALLY don't remember very clearly). I know this is a really vague description, but I'm hoping this rings a bell with somebody, I can't for the life of me remember what episode this is from!!

i think that was either in the eppy "Mrs.George Deaveaux" or The one where blanche goes crazy about Mel Bushmen

isn't that the "Empty Nest" pilot episode? I believe Renee says that to George.
