Adrian is a fun roommate, but he does have bipolar, which is currently unmedicated. And, he can also heal people, however whenever he uses his powers, this makes his bipolar worse. So, they mostly don't let him use it.
Jaina will be happy to see Rey, and that she's working with her in tech. They can do things!
Obi-Wan will be happy to teach her more about the Force.
And, obviously Poe is very happy she's around.
I also have a bunch of kids close in age to her. The younger peeps tend to get together to do stuff. Like they just went on a camping trip. So, that's Adrian, Ben, Jaina, Mason and Rashel. So, they'll all throw themselves at her, since they remember her from when she was here before.
