Aaron Cohen: An unfortunate enemy. He believes mercy is the correct choice. Gabriel believes revenge is. The two will never end up friends.
Vorpal: A fellow vigilante. Perhaps they could work together some day. She seems too scary to want as an enemy.
Simon Dubois: His boss, associate and Krewemate all rolled into one. He's not a great guy, but Gabriel views him as the lesser evil.
Spirit of Vengeance: At night, Gabriel haunts the streets looking for revenge. Either for ghosts he's met or for his Geist. If you're a fellow spooky vigilante, maybe you could team up!
You Gotta Have Faith!: Both Gabriel and his Geist are devoutly Jewish. They go to temple every Saturday, observe the Sabbath and all other holidays. If you also observe, you could run into him somewhere.
Hitman for Hire: Gabriel is not above killing for money. He only takes clients that are bad people, but his rates are affordable.
