Where's Geldoff?

You may not remember Geldoff; he was in Ultimate Spider-Man about 70 issues ago. He was a Latverian high school kid, with the power to make stuff blow up by looking at it (and concentrating). Spidey tried to rein him in, which led to his first meeting with the X-Men, and us learning Kitty had a crush on Spidey and so on. So it seems to be a pretty important arc in Ultimate Spidey continuity, but one very important piece seems to have been lost.

At the end of the arc we learned that Geldoff has been subjected to gene manipulation while still in his mother's womb, and that's how he got his powers. Xavier seemed troubled by it, which probably meant he was going to alert Fury.

And that was the last we heard of it. No follow up. Fury hasn't ever mentioned looking into it, Kitty's never mentioned to Peter (that we've seen) anything about the X-Men investigating on their own. My best guess is that Bendis was thinking about Ultimate Doom being behind it, but the way Millar set up Doom and the Fantastic Four's Ultimate origins precluded it. So he's just dropped it. That's too bad. It seemed like it might have been an interesting avenue to be explored. It's not really viable for Spidey, he's still just a teenager, and international intrigue is still a bit out of his depth. But for the Ultimates? Yeah, I can see them deciding nobody else should have genetically manipulated people but them and their allies, and trying to kick down some doors in an Eastern European nation.
