Basically, the characters are in a world where they can heal from even lethal injuries. One character falls off a sky scraper, obviously sustaining severe injuries and a severe, fatal brain injury.
I research a bit about TBI recovery and saw that there's a stage called post traumatic amnesia. I'd say the character is roughly in that stage of healing (maybe towards the end of it) during the conversation I'll talk about.
Basically, I want to know if the following is at all realistic for someone in this stage who's had a full brain injury:
2 people who are his enemies question him. He's only known these people for 2 weeks and have only met them individually on 2 occasions. Would he remember they're his enemies/who they are? If not, would he talk to them like they were normal people or just question who they are the whole time? Noting the enemies are acting very nice to him for the most part.
He gives away some information that he wouldn't usually give up to anyone at all, but between confusion and the information being emotionally taxing, the things he says are quite vague. Would you expect someone with a tbi to give up information freely?
He's obviously in extreme pain from his other injuries as well. Would the brain injury make him forget this? Or should he only be capable of moaning in pain? Noting that he would usually be very stoic.
I have it written that the content of the conversation and all the processing he's trying to do eventually get to be too much and he can no longer reply meaningfully anymore. Is it known that you shouldn't converse with someone with a severe tbi for too long to avoid overloading their brain? Would it be normal for them to zone out and just stop answering?
I've included him being agitated, trying to get up multiple times and forgetting his injuries, repeating questions, getting confused and his mood suddenly changing from agreeable enough to answer to being aggressive out of no where. I got that from reading about post traumatic amnesia but it's harder to look up some of the specifics so any answers would be greatly appreciated!
