Today's comic is an example of party in-fighting, an inevitable part of any tabletop game. As long as the party doesn't hurt each other, it's all in good fun. Although, technically speaking, and unarmed attack against a 1st level wizard would probably leave him only half-conscious, and an explosion like that would kill everyone in the carriage.
Woops.
I'm actually quite happy with this one, it being an example of why I should avoid just having talking heads. Fun fact: It took just as long to draw and colorize as a talking-head comic.
