Finn's managed to make it out of the craft somehow, though judging by how he's sitting on the ground curled into himself with his head in his hands, he's not doing so hot.

He's only partially healed from the fight with Kylo Ren, and the flight hasn't helped with his injuries. In pain, confused, and utterly lost, he just shuts down for a quick breather. Maybe once he's caught his breath, things will make more sense.
