Charlotte and Bob go to the bar with Charlie and all of those other guys. Charlie does something to piss off the bartender and he pulls a gun-type thing from behind the bar and starts firing. At first I thought it might be a repeating BB gun or something, but they're way too calm for it to be anything harmful. Plus, whatever he's firing looks luminescent.
What's he firing at them? Is it some sort of low-level stun-type thing?
