Cunning and logical, Arbel is constantly measuring his friends, family, and acquaintances based on what they can provide him. It is not that he is uncaring or ultimately selfish; he finds a great deal of value in the fact that close friends and family are able to provide each other comfort and love. It is more that he is unable to see the world through an emotional lens that might be softer and friendlier to those he meets. He is also very self-aware and self-critical, especially about the difficulty he has feeling fully comfortable around other tokotas.

From the outside, Arbel appears somewhat quiet and calculating, but not quite timid as he puts on airs of being confident.
