Yeah! There we go! Train fight! A proper train heist should always have a fight of some kind.
It’s hard to tell, but I think that’s Beckett near the first “rumble rumble...” That’d fit with the command to unhook the rear of the train at least since there’s definitely guards back there. Assuming this is like a real train, we’ll likely have a couple guards realize what’s going on and make it across in time to fight with Chi’ra and Chewie.
Hey, wait a minute; how can Rio fall back? Weren’t there cables hooked up from the cargo car to the hauler? Is this going to derail the train now or something?
