***** SPOILER ALERT **********
I don't think it's a spoiler but some of the more sensitive on that issue may feel it is.
If you think Carter is upset about the Money, sheeesh, were you watching the same show??
he was upset because of how guilty the asner character had made him feel about his life about not contributing, hence the whole going to chechnya thing. and he really looked up to the asner character. it was the total betrayal that upset him.
