I... feel like if I were the bishop I would not be trying to strong-arm the 8-year old who just fended off an army. If he were talking to an adult then maybe, but.
Like he's just shown his attitude towards being subjugated quite emphatically. And if he were an actual 8 year old he'd be high as heck on the power rush right now... Seriously, bad idea.
(MC is nice and won't get violently angry like a real child with too much power might when being bullied like this, so the bishop's probably not actually in mortal peril, but, like...)
