T'Challa and Tony
Tony knew all about how weird it was to have people there that were close, that you knew, but you couldn't tell them. Sometimes he thought that Happy might have caught on, but then he would crack a joke about his bosses' crazy talk and their lack of sleep. Then Tony would stop worrying. At least for a little while.
If it was family though, that would have been a lot harder.
He perked up at the Godzilla mention. That was something he knew of.
"Welp, there was a lot of genetic manipulation going on, and some of the testing was legit. Some of it, not all of it. There were some dead ends on the Dark Web where data was being sent, from downstairs. The head guy killed himself before we could get any info, other than a Hail Hydra."
Tony winced a little before adding, "They were up to some really crazy stuff, gene mods that match with nothing that's been done before. Even beyond what's being theorized. Or what's considered legal. Sure, they pumped them full of super serum, but the gene splicing to get the regen factor in there is nearly seamless. I mean, Cap's got something like that. That quick healing super bod, but this is...whew. Somehow they figured out how to make it almost, but not quite, instantaneous."
