You try to defuse the situation, but Aaron's curious

You decide to give him a piece of your mind and ignore the gun, hoping he'll drop it as he goes to his room. "If there's something in my room you feel entitled to, ask me and I'll help you get it if it isn't mine. If we don't agree if something's mine or yours, we got a problem that we'll have to solve when we get to that bridge. Either way, if I catch you in my room again, I'm reporting you to the police for burglary."

"Fine, fine," Aaron sighs in an exasperated tone, giving the tone of someone who thinks they're the victim.

"We agree? Good," you say as you go towards the kitchen, hoping he'll leave the gun and go to his room before you get back in here.

*Flash*

There's a familiar flash of light, and you look behind yourself to find the gun has been fired. Has anything changed, you wonder for a moment.
