In Star Wars: The Force Awakens Rey saves BB8 from some thugs and just walks away from it, annoyed that it tried to follow her. BB8 chirps something (this whole scene not subtitled) that makes her answer with a disgusted "Nooo".
A few seconds later later, she allows him to follow her.
What's happening here? She saved the little guy and just sent it away, so why save it at all? It's clear that she doesn't make friends and won't try to sell BB8, so I'm confused.
BB8 needs to find people so it can carry on with its mission as explained in this answer, but what's up with Rey in this scene? There's no subtitles to any of the alien dialogues.
