This edit helps cement the idea that these people are a family now, instead of Rey being completely alone on a desert planet at the end. Her friends are there waiting for her : )
It also helps explain why BB-8 is there, he’s just a curious little friend : )
Huh, I would have never thought to do this but I actually really like it. I wish we could see Rey walking past in the background behind Chewie though, just to sell that they’re in the same location. It’s not strictly speaking neccesary though, and I think it works quite well as is.
