Makes sense but I could have sworn this novel was about Jyn’s father and the creation of the Death Star.
If it is Magic Stick Man the problem I have would be smaller but it would still be there. I would prefer his character to believe in The Force but not be able to draw upon it.
I’m pretty sure he would be able to see a training remote with the blast shield down.
If Luke could after a few minutes of training than someone who has been using the Force for years to compensate for sight could as well.
Though if he can only do that then he should have just been a regular character.
