(Canon-fanon fact: one of his various and strange problems is the caring self-pride, I'll explain, being his loved ones all his world, he has develop an ego for protecting and caring for them, so when someone tells him he won't be able to protect his loved ones or one of them refuses to accept his suggestions of trying to make them feel as best as possible, he irritates, not just because he cares about them, also because it works like a wound in his ego lol)

*he got static, like meditating about the current situation, then he glitched bad between snarls and grunts of annoyment, until he turned back to noemal.*
"UuuuUUUUGGGHHHH- FINE, fine, alright, just wanted to make you feel better with that-"
*he snorted but breathed deeply.*
"I'm sorry, okay? Sorry for being such an obsessive guy-
*he said that with an annoyed but more calmed tone*

(Most probably, Canon Line wouldn't do this, but wanted to do the same as when Fae and Line argued so bad, yeh he's my lab rat OC ^^)
