- Why he was suspicious: This rich boy has always been pretty sketchy. It doesn't help that he comes back to Rosewood to meet up with Sara and Jenna. In the wake of Sara's murder, Hanna is determined not only to prove that Noel is behind it all, but that he's also the second child of Mary Drake. And let's not forget: there's video proof that he was in the dollhouse where the girls were tortured.
- Why he's innocent: In the seventh Summer finale, Noel dies by beheading himself with an axe! At the end of the episode, "A.D." is about to go for a drive and is very much alive. So there's the end of that theory.
So who is "A.D."? It could be someone we never met before or another blast from the past. Either way, we've taken three huge suspects off the list.
