I completely rebuilt liberty prime and i betrayed the institute by telling the brotherhood aobut the mass fusion quest. I retrieved the agitator and went back to the airport to talk to proctor ingram. She told me that elder maxson needed to give me an important mission called blind betrayal. After doing some other side quests, i found out that i decided to do the quest, and when i looked at my quest log i found that i had somehow failed the quest. I dont have any more active brotherhood quests other than a few of the repeatable side quests. In addition, paladin danse told me to meet him on the prydwen after the mission where you retrieve the nuclear bombs from the glowing for liberty prime. He is nowhere to be found and when i teleported him to me, he was mysteriously dead. I really was looking forward to destroying the institute with liberty prime, my only save before i failed the quest was over 10 hours of gameplay ago, What can i do?

The teleport was probably a bad idea. The Blind Betrayal quest involves dance being at a certain spot and not being your companion until you complete that quest. I made the mistake of fast traveling from Ingram right when i finished Liberty Reprimed to the airship and i think it was showing me the start of the Blind Betrayal quest. It must be a combination of them

1. starting the quest automatically
2. you not going straight there or you would know why I said what I said
3. You teleporting him thinking he had just gotten lost.

I teleported him because the quest was already failed
