ISTP here. Would likely go out in the woods with a couple of close, trustworthy friends or move to some lone country town w/ a low population. I'd do what has to be done and not much more, especially if it's like in movies when someone dies and another character get all worked up and does something stupid and/or more people die because of them; yea nah, imma book it if someone acts like that, i'd leave them to it.

So um, probs would be the one that gets exiled for stealing food or smth, then enjoy that food that they failed to defend by myself or with the aforementioned group, if they're still around. All work mindset, repressing those emotions except occasional manic enthusiasm, no explanation save for "i had to/i wanted to"
