The first part is the hardest to get his head around. I was murdered. Dead. She died. She said it once already, but having it reiterated and explained somehow doesn't make it easier to comprehend. Nothing brings back the dead, not even the Force--

Except here. Cassian, Jyn, who else? Death isn't what it used to be in his mind, now a nebulous question instead of the end of one part of existence and the beginning of something else.

Maybe that's the way to look at it. Her life ended, terribly, and she woke to the start of a new one. He doesn't say he's sorry for what happened to her. He's heard so many people say I'm sorry for your loss, pain, experience that the phrase means very little to him now. Instead he just reaches out a curled hand, brushes his knuckles against her arm.

Still there. Still not running for the jungle.
