Sara Harvey became one of the most polarizing characters on the show, for the sole reason that she seemed to be created out of nowhere. We learned about her existence several seasons ago, when the Liars found out that she went missing on the same day as Allison. She didn’t seem to play much importance until she reappeared in the Dollhouse, and then was revealed to be both Red Coat and Black Veil — a plot twist that many found to be quite anti-climactic.

However, this Tumblr theorist thinks that there might be more to Sara than we currently know. According to her post, there’s evidence that could prove that Sara used to be in Radley (just like Bethany) and that she makes several references to images in Bethany’s drawings. We also know very little about Sara’s family, which would align with the fact that Bethany’s father had an affair with Mrs. DiLaurentis. If Sara turned out to be the infamous Bethany Young, her character might have a greater impact on the series than we ever imagined.
