Reflex/Ready actions are great for firing instantly at enemy mooks. Also great for firing instantly at allies!

Oh. Well then, that was easy enough.
I'm actually a little shocked that there wasn't any extra stuff between Rey climbing out and meeting the rest of the group. And now I'm even more confused at why Rey went inside the wall. Was it for harvesting material for something like near the beginning of the movie? She doesn't look like she's carrying anything extra, and there's not going to be any time to craft something either. Like, the only way this makes sense to me at the moment now is the way the comic has presented it, which doesn't feel like it'd be a good cinema scene.
Ok, so I'm pretty sure Han/Zeppo isn't going to get shot by Rey. Finn? Finn might get shot. Probably not a killshot, but Rey was very not happy with Finn over something last time she saw him. The question for Rey is, does this look more like a rescue attempt interrupted or more like a trick to recapture her? We already know weird visions are a thing; maybe there's another new Force Power that Kylo could be using.
GM: The coast looks clear.
Rey: I climb back up the wall to the walkway.
Finn: We’ll go around to the corridors on that side and pick her up.
Rey: I need to find a map or console so I can locate the control room.
Rey: I’ll prepare a Ready action so I can shoot as soon as I notice any movement.
GM: You turn a corner and run into Finn, Chewie, and Zeppo.
Zeppo: We freeze!
GM: Reaction rolls to see if you can freeze faster than Rey can shoot.
Zeppo: I rolled a 9.
Rey: So, I need to roll lower?
GM: Well, higher would be entertaining, but sure.
