I got to the institute by means of the minutemen. I did their first quest (because it was to take down a raider) but didn't go back to the institute yet. I delivered the data to the Minutemen and I brought the serum to Virgil. I then went to the railroad to see if I had pissed them off. No I did a misc quest for them and got another one but Desmonda (sp?) keeps asking me to work with her instead of the minutemen. I'm not really inclined to do that but is that the only way to get the Ballistic weave?
What is the implication of saying I will work with them instead.
