Original Commentary

In the last panel, beneath the thought bubble Brisbane is holding his weapon. I didn't realize until I started coloring that he's holding his knife upright, very close to his crotch - it looked wrong, especially with the heart slime right next to him. So I took the traditional cop-out of putting a word bubble on top of it.

Yes, those are Joy's colors on Kimberly. Note that the wizard (third panel, looking afraid) also has bunny ears too - Isabel

Modern Commentary
That was the other part of the joke. Joy's in-game character had Kimberly's colors and vice versa... - Terrence
