"If you want the short version however, then I had a good idea and I sent it to Heph. And then I got an interesting response back."
Preposterous! Now this man is slandering the good name of Hephaestus Administration, and most kind Head of Science Dr.Sanctor!
Your regular trooper wouldn't quite get that 'sent a message to Heph' could possibly mean something other than 'sent a message to Heph crew' (like, instead, 'sent a message to the Doctor currently residing on Heph'). The resulting conclusion, of course, is that it was replied to by none other than probably the guy in charge of weird science on Hephaestus, i.e. Maurice Sanctor. And now Xan is going to add Maurice to his Book of Grudges. Pity.
Flint is leaving his response deliberately vague when there is chance for controversy so that he can tackle that if Xan brings it up and prevent vendettas.
Of course, Xan can always start vendettas for poorly thought out reasons and insubstantial evidence, as often happens in RL, but there's not much I can do about that. Flint will try to be close to him to keep an eye on him if he determines that his actions have led to the creation of something potentially dangerous, but if he is put in different teams, there's not much he can do.
Anyway, what are you afraid of? It's not like he can do much more than try to multi slap you to death and he has terrible strength from what I remember. This thing wasn't designed to be a combat suit, it's a support suit, meant to stay in the back. Unless the ones that made it decided to upgrade it or Xan suddenly uses his newfound powers of token inflation to generate a mountain of tokens and buy tons of tokens, you should be fine.
Edit: I really hope this thing could become standard armory equipment though. It would be perfect for a flesh tech, because it is made for support people that stay in the back and fight with drones or other aux equipment. And I think Xan has terrible Aux.
