Character Analysis
Doctor Bruner heads up the hospital where Raymond is a patient, and serves as the trustee of Raymond's inheritance from his father. We don't get any deep background on him, but we know that he really cares about Raymond's wellbeing—which is why he's less than thrilled when Charlie takes him away.
However, he seems generally nice and patient when he's trying to get Charlie to understand Raymond's special challenges, and never seems to get nearly as annoyed as he should at Charlie's sometimes stubborn and selfish behavior.
