[Perry stays where he is, not moving any closer to the couches. He doesn't say anything to the first remark, just watches as Arthur gets comfortable.]

I don't want to hit him. [He says it quietly, in a very neutral tone, meeting Arthur's eyes. There's a fine line he walks when he talks to his warden--and everyone else he hates on the Barge--between holding his silence and playing the sarcastic antagonist. The satisfaction he gets when he pisses one of them off feels too good to be comfortable and his anger flares too easily. It's not that he's scared of them; he's scared of himself, of what Arthur wants him to become, of turning out like dear old Dad.]
