That might be a good idea.
Nev, if you go with Finn killing the villager, I wonder if it would be easier fx-wise to have Finn turn the corner, shoot the villager, but maybe cut on the impact to the shot of Finn. Then you could add foley of someone falling to the ground in pain, while Finn lowers his blaster realizing what he has done.
Because as it is now, it feels like it would be hard to make it seem like she has actually been shot, based on her reaction.
Also, how would we know it was Finn that killed her if he doesn’t have his blood marks?
