Klaus is a damaged, fragile man who covers his pain with self-deprecating humor and cynical hedonism and has rebelled against his father by refusing to be the hero he wanted him to be. He plays into the role of an unreliable, unrepentant leech and drug addict, and as a result, his opinion is often dismissed by his siblings. However, he is shown to have a deeper insight than assumed and has even shown to be a voice of reason to his family's impulsive decisions.

You're Dave, soldier in the war.
