Finn had been inconsolable, worried for Rey's safety. Not to mention a damn chatterbox. Han had been worried on a lower level, but he had an inkling that Rey could take care of herself. Chewie just felt cold and wanted to get back to the Falcon.
Han enjoyed finally hearing the end of Finn's commentary when he noticed a girl climbing the enormous side of the hanger through the window. He knew that one was smart. Naturally, this kid, the 'resistance' or whatever he was, took a minute to catch up. Apparently stormtroopers didn't come natural to picking up on body language.
Everything was going smoothly, it was almost too easy. They were close to completing the mission and returning to the ship.
And then a figure clad in black and a helmet came walking across the bridge below them. A figure that Han had known their whole life, but had only seen once in the past few years when they stole Rey away in their arms. The same figure, that Han's estranged wife had begged him to bring home. The smuggler in Han wanted to ignore it and leave, he had a bad feeling about this. But his paternal side, the side that had tried to give the best of everything to his son, wouldn't let him move.
A feeling of deja vu came over him, but it was his son and he couldn't abandon him again.
"Ben!" he shouted. Han's voice echoing.
The figure halted, looking directly at him.
….
What had been done could not be undone. Ben Organa Solo had killed his father. Watched as his body had fallen off the bridge, and then turned his attention towards the traitor and the scavenger. They ran and he followed, managing to cut them off in the woods. The two had a headstart, but he knew the territory better. On top of that, Ren was still flying on the emotions that killing his own father, no, Han solo, had brought on. He was pleased that Snoke would value him more, but a part of him, the part that he tried to bury, had fractured. He knew immediately that his mother had felt Han's spark go out, he could feel her anguish. The small feeling of guilt sprouting in him further pissed him off.
Somewhat limping through the snow, he waited, activating his lightsaber when he spotted Rey and Finn running towards him.
