There appears to be a disconnection between the affinity changes generated and the actually spoken responses, for many of the companions.

Alternatively use a chair inside Nahant Sherrif's Department to fast forward time for the fight to end. If this happens, proceed to Gabriel: X6-88 will teleport to the Sole Survivor upon entering the captain's cabin at the top of the ship, and the quest will progress from there. Since X6-88 is essential, he cannot lose the fight but will continue to fight ad infinitum. The Brotherhood members will not be hostile to the Sole Survivor unless they are already an enemy of the Brotherhood of Steel.

When meeting up with X6-88, he may be under attack from a Brotherhood of Steel team and a Vertibird.

Tell X6-88 you would like to avoid violence

Tell X6-88 it's inhumane to destroy Gabriel's identity He said that I would find a stock of useful supplies waiting for me there. The mission to reclaim the rogue synth at Libertalia is over, and Shaun has asked me to visit the personal quarters he had prepared for me. Now I need to return to Shaun and tell him that the mission was a failure. Unfortunately, the rogue synth was destroyed. Shaun asked me to help reclaim a rogue synth who's taken over the raider gang at Libertalia. I've joined forces with a Courser named X6-88, and together we'll confront the raiders and bring the synth home. I'll meet up with a Courser at Libertalia to begin the mission. Shaun asked me to help reclaim a rogue synth who's taken over a raider gang. Upon entering them, the mission is complete, and the Battle of Bunker Hill begins. Upon returning to the Institute there will be another discussion with Father, and he will provide quarters for the Sole Survivor. This will also trigger different dialogues from many of the Institute scientists and Father. The player character can kill Gabriel, much to X6-88's dismay.

Once the fight is over, X6-88 will teleport out with Gabriel. There are a couple of persuasion checks that give extra choices like the password for the Master locked terminal that can open a nearby safe. Using the synth's factory reset code will disable Gabriel and keep the fight limited to a few raiders. On reaching the top of the ship Gabriel will initiate conversation, and no matter what, a fight will break out. Upon entering the cabin, the courser companion, X6-88 will initiate a conversation and provide Gabriel's recall code. Once he is collected, fight along with the network of ships until the target is reached. There will be a courser companion at Nahant Wharf or the shore northeast of Nordhagen Beach, depending on from which direction the player comes, who needs to be collected first. Speak with Father about the Institute, he will request help dealing with a renegade synth turned raider at Libertalia.
