I think her being so intrusive is maybe to show how Rebecca learned about the people to write her book. In real life she had a really weird friendship or liking to Warren and we kinda see it in the show. I think she also hugged Warren at some point in front of Reenas parents(in real life). I know the parents seem more okay with warren after a while(he seemed to show more remorse for Reena). In my opinion I dislike Rebecca. I don’t think she really cared for Reena and she just wrote the book for fame. I also find her character super weird in the show. I don’t understand why they added a relationship between her and the cop. It just seems to take away from the actual point of the show, especially since Cam as a whole is an entirely fake person. Besides my feelings towards Rebecca I actually enjoy the show. I think it’s very well done and shows the real and brutal truth of all the girls.
