Well, jumping in your tank was a bit over-the-top, Karoiga. But I can see why he would do it. It's his preferred place and he can use all the sensory equipment in there. Wakefield might put a note on your psyche report, but that's about it. I'm gonna work into the backstory the fact that a lot of the hardcore soldiers on this expedition have gone a little "strange" during their time in the shelter...
Jigoku, take my advice and listen to Woodrat. He knows what he's talking about.
They'll be plenty of opportunities to show off your stealth skills as the story develops. You don't need to prove it by fucking around with your own people. And like Woodrat said, the game won't be any fun if you're psychic.
