Making Barney/Alyx/Grigori join your squad?

[Flubadoo]

I know its possible. I've done it before, but now they just won't join. How do I make them?

[CoolCorky]

There was an NPC faction tool or something that made any NPC act like a rebel/citizen

[Flubadoo]

Well can you make them join without it?
