I want to do a MM ending. I used the MM to get into the Institute. I finished Bunker Hill for the Institute, but now Mass Fusion is starting and I can't find an opening to get kicked out so that Forming Ranks for the MM can start. I do not want to just murder someone in the Institute to get kicked out. Is there some other way to get kicked out? I want to leave the Institute.

Thanks.

Have you try starting Mass Fusion, informing the BoS, Entering the Vertibird, making you the enemies of the Institute, thus starting Banish from the Institute?
