His blaster wound not healing was a metaphor of him being independent from the movement and not being able to move on from his trauma. He’s fighting accepting his losses when he’s fighting getting force healing. The act of getting it is him accepting he can’t do everything independently, and that he is part of the movement, no longer and individual, and moving on from his losses. That’s what allows his trauma to start healing.

This concept could be handled in countless other ways. My main gripe is that the show and rogue one focused on how the rebellion wasn’t built on zealotry or a single hero but the sacrifice and grind and passion of a great many people working together.

But it’s Star Wars, they gotta jam some lucas spam in there somewhere. I’m glad it was limited to this.
