I've seen tips that my companion is in trouble or that I should give them a Stimpack, but I've never had an issue of my companion dying.
Can companions die?
I've also noticed that sometimes they will just walk in my line of fire and I'll end up shooting them a couple of times with a machine gun or something.
Will they change their view on the relationship if I shoot them?
Best Answer
Followers can not die. Also noted in this article about companions that can't die.
Since they can't die, doubt shooting them will bother them much.
