Scott will be focusing on keeping people safe for the most part. When it comes to not knowing what to do, his default actions are to look out for everyone until someone else (see: Stiles) comes up with a plan. That's likely where he's going to be focusing.

During the riot, Scott will be doing everything in his powers to calm people down. There will likely be a moment in which he roars in general, and then toward some specific individuals if it comes to that (animal-type people and if Scott can sense that in them and if you're interested). Otherwise, he will be the type trying to get people to safety.

Keith on the other hand is going to be a man on a really futile mission, so if anyone wants to join him on that, I'm game. His number one goal will be to hijack the ship, or ships that can come to the ship, or whatever, though most of his information will be nonexistent. Whatever. He can do it. Probably.

This will culminate in him trying to use the riot as a chance to escape. If anyone else wants in on this, it will get people put in solitary (as that's definitely where Keith will be ending up). I'm game for Keith's impulsiveness being fed in to or worked with by other people and all of them getting into a lot more trouble as a result. I think it'd be fun.
