Well yea, that got addressed. Something he couldn't just openly rant on. She wasn't supposed to find out- Zack blew it.

They brought it back up in a couple quiet ways. The one I remember most was something when booth was ordering the hooker in LA. Something to the effect of "Hey, how come I don't get to go on these trips?" and Booth says "becaus you have a significantly larger weekly allowance than the rest of us." Something to that effect, I could look it up.

Something else too, I think, but it's stragely not jumping to mind.
