In this clip, Caleb confesses that he's the reason Hanna can no longer visit Mona. He calls it an intervention, she insists he doesn't understand the situation, and it doesn't look like either of them are backing down.
After surviving everything Mona (Janel Parrish) did to them as "A", will Haleb be torn apart by the question of what to do with her now that she's just a girl in an insane asylum?
