Who Drew the Death Card?

We've got a spoiler that says: There will be at least one character death that comes as a complete and total shock to the fans.

I know you've been talking about it already, but I thought I'd pull it out and make it an official Death Watch Speculation. So who do you think is going to die? My thoughts change from minute to minute, but alas, I'm certain it's not going to be Teflon Jack. Everything, including the possiblity of death, just rolls off his back. Too bad it couldn't roll down his front and get stuck in all that chest hair.
