I loved Fallout New Vegas. It was my favorite.(Sorry Fallout 4!)I played Arcade in a game a year or two ago.
Anyway, I'm Patti and I'm not too sure Ray and the Courier will have much interaction since he's with the Survivors. They do have the whole bleeding heart thing in common and he, currently, has a fondness for thieves. He has one of his very own that he tries to feed vegetables to.
