Done with the Brotherhood, now I'll soon turn on the Institute to further aid the Railroad. Father has given me an order to kill the leaders of the Railroad, that's not what's gonna happen.

I think I've done all the quests I want and found everything, but just to be sure - did I forget to do or find any special things in the Institute? Thanks in advance

You'll probably want to buy the Legendaries offered at the Institute before pulling the trigger on them, if you want to have them.
