You and Connor just made it home from a stressful day of work, when Connor was forced to make the choice to either shoot or spare a pair of deviants he'd chosen not to. Connor showed those deviants sympathy, something that just isn't programmed into his system. The second you both stepped foot into the house Connor was off, closing himself in his room and locking the door behind himself. He knew that something wasn't right, he even self-tested himself at least twenty times just that afternoon but found nothing.
Now he's pacing his bedroom, self-tests going one after another as he tries to pray some sort of programming issue into existence. He knows what's actually happening, he's beginning to deviate and that scares the shit out of him. He's too scared to even face you after today so when he hears a knock on the bedroom door, he immediately pauses his movement, not sure of what this will help but finding i to be the only solution he can come up with.
