I think his responses just show psychopath tendencies. He has no empathy to how others think, so in his mind his response was adequate enough to explain and that should be the end of the story, he can’t comprehend why others would want to dig deeper because it doesn’t make sense to them, but to Prick it does and therefore everyone else is the crazy one.
I think it also answers a lot about pouty, he has learnt not to have a voice and always take a step back, in literally everything. He doesn’t challenge, he barely has an opinion, Prick rules where they go, what they eat, who they see and is even one step or more ahead when walking. Pouty has learnt to shut up, put up and stay behind.
