The grip on his arm is almost painful, the pressure sensors indicating his strength is bringing the bionic close to it's breaking point. He doesn't look away, not even as that fire laps near him, that darkness drowns out his own ghosts. He didn't- He hadn't meant it. Still didn't believe that he would do such a thing. Had spoken out of anger and trying to place his own self blame on someone else. And it stings, to know he's hurt the man who... Who gave him a second chance.

He swallows back his pride. His anger. His grief. Leans forward slightly, shoulders slumping, letting all that fire burn out and be replaced by the waters of grief. Maybe Reyes had a reason for joining Talon. Keeping an eye on them, running interference. He'd spared McCree when they'd fought before, hadn't he?

"... I'm sorry." He needed to stop running. He needed to stop running and face all the decisions that he made. "I'm so... so damn sorry..." The tears that have been pricking at his eyes spill over, and he tries to keep his voice from shaking.
"I asked you to come with me. A-And you said you couldn't because you had too much to do. An' I shouldn't have left, I shoulda stayed and helped you and then you were dead, Gabe. You were dead and I had nothin' but an empty casket and the lessons you taught me-"

The ghosts are starting to fizzle out as he lets go of his grief, his anguish. As he lets all that guilt well up inside of him.
"Maybe you didn't have a choice, but I did, an' I made the wrong one. I shoulda stayed. Dammit, I shoulda stayed."
