i saw that you reblogged the thing saying maybe sara really is bethany after all but how i saw it was that B really is dead and after sara ran away she realized that she had no where to go and probably no money so when cece found her she went with her and like cece said the game was a drug so sara probably got too wrapped up in it as it went on plus S's friend recognized her so it has to really be her
I still think that it would have more meaning if she was Bethany and that Cece was still her friend after all these years and she was lying about hating her in Radley and that the “Sara” thing was her cover so that she could “stay gone”. I guess for that to work they just needed to make Claire (Sara’s supposed friend) have been employed by Cece&Bethany to make the story more believable.
