Oh hey, I guess Rey is going to get in on the boarding action too. And it's a reasonable enough way for her to get into the current conflict area as well, even if there's still the dilemma of how she gets onboard the Supremacy with such a tiny pod. Flying in behind the mess the Raddus makes with its boarding perhaps? Or maybe since Kylo was talking to Rey before all of this, he'll have a tractor beam pull the pod in once he realizes she's nearby, assuming he picks up his Force Phone to talk again. It's still weird that that's actually a thing, but now it's gotta be considered as an option.

Really, the bigger question I've got is why bother with escape pods on a ship as small as the Millennium Falcon? It fits here as a way for characters to jump around the plot, which I like, but there's not much room in that pod for..... well, anything. No food, no water, no hyperdrive, definitely no room for another person.... And with how big space is, that reads pretty much like climbing into a coffin to me like the comic alludes to. If this was a different sci-fi universe, it maybe could do some hibernation or stasis thing while a rescue beacon broadcasts the pod's location. Maybe it's actually a smuggler's drop pod? Han and Chewie did a bunch of smuggling when they were flying the ship, and I can't see a reason smuggling pods would be removed just for Rey to fly back to Tatooine with the Falcon.
