Welcome! MJ here, we already know one another and I am familiar with your PB but new concept so that's fun for me.
As always I have a small army and information on them can be found here so have a look and maybe something'll strike your fancy.
The ones most likely to interact well with Domino would be Cameron, Elijah (possibly), Gabe, Jesse, Roman and possibly Rhys. The others I'm not sure about but would happily and readily put them in scene to see what happens as sometimes random encounters make for the most fun and the most surprising of character development.
You know how to reach me if you want to talk anything at all so hit me up, but again, welcome.
