8, 29 and 59 for ya boi John Halo
8- Favorite indulgence and feelings surrounding indulging
Oh Johnny boy is a mess, I think if his brain tried to load the concept of "you deserve nice things" it would just go "you are alive and that is a nice thing already". He is definitely the kind of guy who has a passion for guns, but I don't know if that can really counts
29- Reaction to sudden extrapersonal disaster (eg The house is on fire! What do they do?)
If it's a "material" problem, simply figure out where is the problem -> find solution.
If it's something that has to do with feelings...oh boy. Tries the same thing, but it doesn't work, so he just panics because he has no control over the situation, but he refuses to show it, so he just tries to mask the problem (probably not well) until he eventually breaks, but it's still an...unusual way of breaking. The conversation between Weapon and him in Infinite with her asking him something along the lines of "Chief, are you okay?" answered by a simple "...No." comes to mind.
For this one I assume you meant 49 since there is no 59? So uh ye
49- If this person were to get into a fist fight, what is their fighting style like?
He definitely would one-shot most people with a single punch to the face, don't think he really follows a proper fighting style. I don't feel like he would punch to kill in case of having to deal with a human, but overall just protect vital points, punch to vital points. If he finds something on the floor and you happen to be an evil alien- can't be a war crime if they are not a human ¯\_(ツ)_/¯
