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

If Rollins never checked into Radley Sanitarium as a patient, there's a strong possibility he worked there as a doctor. It provides another opportunity for him to have met Charlotte, long before her infamous "A" reveal. It also gives Dr. Rollins more motive, and a more tangled involvement in the mysterious roots of Rosewood. This could be the missing link we're looking for.
