Moving Starkiller to fire at the end of the lightsaber battle is interesting.

I do like that it does not take away from Han’s death. I also like that it makes it seem that the instability of the planet is what causes Starkiller to reach its own destruction upon firing.

The only thing is that I feel like there’s going to need to be some dialogue here to piece that part together. Like it would be perfect if there was a First Order officer that mentioned something about the instability of the planet.

This idea is something worth continuing to play with.
