"Pretty Little Liars" Season 5 is set to air its 100th episode on Tuesday. Several cast members gave a few insights on their interviews.
Caleb (Tyle Blackburn) told a hint on TV Line about Caleb's big change. "His time in Ravenswood has messed with him greatly," he said. "He's questioning his sanity, what life is, what's real and what's not. So he comes back to this hyperreality in Rosewood, and he's just overwhelmed. He's angry, he's confused, he's sad, he's mad - all these things. He has a dark side now that he really didn't have before."
