In need of some help with this one. I'm not sure if there are any known fixes for this, but if anyone knows anything. Some help would be much appreciated.

I had Paladin Danced as my companion while traveling around Cabot House. I had a sentry bot attack and so I killed it, but once the bot was dead Paladin Dance asked where I should send him to(like when you dismiss a companion). Now he turned hostile towards me and when I return to Prydwen he is inside and keeps shooting at me. This is making it a little difficult to navigate the ship for my missions.

Recruit another companion, equip him / her with a strong weapon and have them kill that [censored]

if your weapon is out try holstering it. You may have shot him by accident when fighting the sentry. Typically if you hit them by accident and you holster your weapon they'll realize you didn't mean to just like with past games
