Ones with dialogue you can unlock, not like Dogmeat who doesn't care and can't talk.

X6-88...

Other than that though, the best you get is companions not caring too much about whether or not you side with them. The ones that come to mind are Codsworth, Strong and possibly MacCready.

Cait didn't seem to mind. When you destroy the BoS, she actually praises us for taking the fight to them.

off-topic, but I wish you could take Curie to the Institute. That's the one place in the whole Commonwealth she would feel at home, but she can't go, even after you take it over. There are lots of loose ends like that

(Nick complains about the BOS, hating on them for "trying to wipe out his kind". Then when the BOS destroys the Institute he's like "yay! no more bogieman!".. um what?)

Yea, this really kinda bothered me when I went to talk to everyone after the BoS ending. Preston yelled at me for not evacuating the Institute, but Nick was totally cool with the fact the group that wants him and his kind destroyed for existing now pretty much rules the Commonwealth? Really, Nick? Not a single complaint about that? After all that dramatic Poe-quoting and hating on Maxson?

On topic, I'm pretty sure only X6 actually likes you working for the institute. Unfortunately, he's currently bugged for me and I can't recruit him at all, anyone know if there's a way to unbug him on console?

Yeah, Nick's "Yay! I'm so glad the faction wanting to see the eradication of my kind controls the Commonwealth!" reaction is very odd coming from him. I just handwaved it to him hating the Institute more than the BoS. At least the latter's honest about what they're doing and he's survived for God knows how long as a Synth.

Well that's disappointing. I was considering one RP where I romanced her and we would live at the Institute. Does she just say "I'm not going there" or she just won't follow you or what?

Does Curie have dialogue related to you choosing to work for the Institute?
