You make some really good points about Chase. I wouldn't necessarily say myself that Chase is indifferent. I would peg him more as being able to see more quickly than either Foreman or Cameron the right thing, or the necessary thing, that needs to be done. One defense that I can offer for those who only see Chase as a suck-up to House is how he is always obedient, not really subservient, to his father. His father has a very authoritative personality, and so does House. Thus. Chase feels that agreeing to the person in charge is the best option.

I also like how you compare Chase to Remus. I also see Remus as not necessarily indifferent but struggling to do the right thing. He also does not like being judged for who he is on the outset, being a werewolf and the social isolation that comes with it. Thus, I believe that to be the reason for his very strong personal convictions about morality and right and wrong.
