Hanna (Ashley Benson) and Caleb (Tyler Blackburn) are one of Rosewoods more stable couples, but Caleb's dark new attitude will create another rough patch in their relationship even now that the pair's Travis shaped speed bump is in the rear-view mirror.

You're kind of wondering, 'What's gone on?'" Blackburn told The Hollywood Reporter. "As the episodes go on, he starts to describe everything he's been through in Ravenswood. He comes back very damaged. He's just angry - he has a big, big chip on his shoulder."
