Nick Valentine stole my BoS power armor when a random settlement attack happened. He wouldn't get out of it so I just took out the pieces of armor and left him in the frame. I had a T51 power armor in the settlement and swapped the B0S T60b pieces. Anyway, now he's almost unbeatable. He tanked vs a sentrybot for me the entire time I was popping fusion cells with my fully modded Old Faithful. I wish I could put dogmeat in a power armor frame. LOL. Kind of OP that he can run with it without a fusion core. But now I can walk around without any worries. PS4 Survival difficulty

Talk to him and you can tell him to get out of it
