"Haunted" would be a good word to describe Revenant. His eyes always seem to be staring into nothing, he moves slowly and deliberately, and it often seems like he can't or doesn't care to hear when others are trying to communicate with him. When he is surprised--whether jokingly or by an attack--he'll respond with a quick, sudden burst of aggression, before descending back into his quiet persona. Some would call his mannerisms disturbing, but the ones who truly understand him would describe him as lonely. The only one who he shows any affection toward is his adoptive mother, Gwendolyn.
