My wife has been rereading all the books in anticipation of the finale. She's thinking that there'll be a Victorian style epilogue that will establish that Harry married Ginny and became a very stable teacher of Defense Against the Dark Arts. I replied that I didn't think that was a good payoff, but that it would provide the launching point for a new series:

Welcome Back, Potter.

Maybe a second renaissance for John Travolta's flagging career, as Professor Barbarino.

Visible mojo for both Strangler Lewis and iSm. It's too early to laugh so hard.
