Pretty Little Liars: If Dr. Elliott Rollins Isn't Who He Says He Is . . . Then Who Is He?

Dr. Rollins may be a doctor, but he's clearly got a crazy side. We see how little control he has over his emotions as he tortures Alison in Welby Sanitarium. Plus, there's something seriously creepy about his surgical bag with all those sinister instruments. It's possible Elliott was once a lot worse. Maybe he spent time at Radley at the same time as Charlotte. After all, he had to have fallen in love with her somewhere, right?
