The rules clearly say at the start of your turn. If you allow Cat to bestow Life Giving Force at any point of her turn, we won't say no to this advantage.
Ah hostages, such a bother here. Back when I played Rimworld, we'd use them for organs and spare parts for any colonist that needed them, replace their missing parts with cheap wooden parts and set them free. Occasionally we'd take an eye or ear or arm just for spare parts. It's good to have a spare hand and fingers around. If they had any bionic parts, we'd confiscate those too sometimes we'd have to make a cheap mechanical heart or lung so we could have their bionic parts. I would think you could set them free. At this point you already set some free, others were looking for you, one escaped, you've got a growing reputation and the makings of an army who know about you at this point, this won't set well at all with the bandit guild or whatever organization they have, torturing them when all they were trying to do is ask the time of a passing trader, sieging their reinforcements they so carefully set up, mutilating their pets, threatening them, killing their elite members in cold blood... Wow, I guess at this point it hardly matters what you do.
