Dave is an outgoing and rather unhinged man, showing no guilt for the crimes he committed. While he can be outwardly friendly to others, he's not afraid to kill them at a moment's notice. This is due to Henry tampering with his brain, messing his mind up to the point where he genuinely cannot feel empathy for the things he has done.
Bright, informal banter with sudden, chilling calm between jokes; never shows remorse.
