Yeah, I think in that episode he was talking about how their weekly allowance was higher than his when they were in the field. because remember in the 'Man in the Bear' episode when Brennan teased him about getting more money than him for her daily allowance from The Jeffersonian. Remember she says "I don't have a limit." So that's what I think he was talking about there.

I need to go back and watch all this past season. Pay more attention to Hodgins and Angela in the earlier episodes. Hehe.
