I wish there was a quest related to her. Specific to her, that lets us recruit her as a settler :[

Why? She's a singer, why would she goes to become a farmer? I'd rather if there is a quest to bring her to Diamond City where there is a bigger stage for her to sing and maybe clear the Scientology group and let her form concert there or something.

Maybe you build a classy bar & unlock special "stage" workshop item.

I guess it would be cool. Like you can keep the Beer robot. I guess there are enough settlers to manage that we could spare one for Magnolia. Still, I don't see why she would abandon the entire city worth of people for a unsafe settlement for barely 20 people that often raid by monsters and robbers.

Maybe somebody will make a mod so you can change the combat zone into a stage for her or something. That would be pretty neat.

My settlers need some entertainment anyway. Bringing her in would be pretty cool, but she really does 'fit' in the Third Rail. I wouldn't change a thing.

Have an free room in the castle who could be nice to move the bar into, now add an scene and get beer buddy to stay there and we are talking.
