Love how unsettling this is. The puppy act juxtaposed with... everything else (⊙…⊙ )
Very scary! Very Tense! Bet that 'safeword' is some kind of trigger related to his reason for revenge (someone's last words, maybe...?). If so, he knows exactly what he's doing, and, yikes.
"I have to succeed in order to invalidate my parent's lack of love for me (because that'll totally work, right? I'll feel better then, right?)"
Aaaaaand then this happens.
Scared-horny is my favorite flavor of fictional uke, tho, and I'm getting fed with that.
