Gangster

Jonah Raver was a gangster. Arthur noted that fact silently as he saw the handsome man kicking the mummy to death while cursing it. The mummy was issuing some unknown sounds, probably begging for mercy. 

"You little shit, you think you can bite me with those teeth? My ancestor has better teeth than yours!" 

Arthur thought he must have special hate toward the poor mummies, but it was proved otherwise soon enough. Jonah Raver hated nothing; he was simply a gangster. He did the same to a giant beetle that happened to cross his path. 

"You can go ahead, Boss." Very gangster-like, he started calling Arthur Boss. Arthur felt weird that a young man his age was this submissive. However, he started calling him boss after Arthur took down a scorpion-snake hybrid.
