Peter is depicted to have a bombastic and loud personality. He often speaks in a vulgar and hyperbolic manner, including using crude words and swears in most of his sentences. He is defensive when it comes to the people he is close to and is willing to do anything to protect them, even if he goes too far. He claims to be protecting Shai from Alfred by upsetting him multiple times and calling him a bad father and person.
He says the word fucking in almost every line he makes.
