Original Commentary
This is a reference to this comic. I don't imagine that Sofia's gotten much better about buying presents for Kimberly or anyone else. My goal, throughout all of this, is to remind and reinforce character traits. I figure this says a lot about Brisbane, Sofia, and Kimberly - Terrence

Modern Commentary
We all know that Brisbane is going to end up providing the fifty bucks that Kimberly gives Sofia and the fifty bucks that Sofia gives Kimberly.

That's the price he's willing to pay to keep up the polite fiction that they get along. $75 each would be ostentatious and $100 each would be far too much - Terrence
