Well, they misspelled his name on the computer screen but Madison Jeffeies (sigh) name shows up on a computer monitor in the new Age of Apocalypse #4. Unfortunately, it's a list of bodies that are about to blow up, never to be reincarnated (there's been lots of that going on in this series), and later in the book, the whole place go BOOM. OH well, so I guess he's still dead. I was hoping he'd be among the reincarnates!
