Data's being collected on the portal appearances, at least in the Helicarrier. (Yes,
plural. About half a dozen more, since the first time. Most of them with me.) There's a traceable energy signature, it's just a matter of scanning for it, preferably
before I walk through the door.
We still haven't been able to neutralise them, though. I've got some good people on it, but they aren't the best -- Reed's off with Sue still, after all, and Hank... is needed on other projects.
Like refining the SPIN tech.
I'm almost thankful for the Nexus, for the possible warning -- some version of Bruce (looking for all the world like some barbarian warlord) that's captured some version of me. Somehow. Of course, there's an excellent chance that it's somewhere extremely (or even not-so-extremely) diverged from our Earth...
But we do know, in
our universe, that his ship didn't arrive on the right planet. And two plus two is more than enough reason to worry.
