i cant load a previous save, and i killed the turrets because course of habit. and he will turn green if i wait but if i go up to him and try to talk he will shortly show "press x to talk" and then he will turn red. i really dont want to restart the game. though im only lvl 14 yet so it wouldnt be that terrible redoing 3 days of progress. plus if i focus on the story missions. any suggestions?

Go someplace else and wait for a day or two. Come back. If he still attacks wash, rinse, repeat.

ok thanks man, i think ill do the brotherhood missions and find danse. will the turrets and the robot respawn if i wait long enough?
