Alhaitham is without a doubt a thief. He steals things to benefit himself and not others. He’s calm, collected, and appears serious. He talks in a formal way. Despite stealing, he still pities people despite his ego. He’s never had anyone be nice to him before, so any gesture is foreign to him. Other people describe him as emotionless, though he does that to protect his own feelings. His feelings are complex and won’t show them easily. May sound harsh, but is just trying to help. Very smart.
