Credit: Marlene King Instagram Photo: Ashley Benson and Tyler Blackburn Film Last Scene

We’ve known about it for months now, but it felt like the day would never actually come: Tyler Blackburn’s (Caleb) last day of filming as a Pretty Little Liars main cast member. Check out this pic PLL showrunner Marlene King posted of Tyler and Ashley Benson’s (Hanna) last scene together. Cryers beware.

“My babies,” Marlene posted along with the pic, which shows Ash and Ty looking sullen in character on a Rosewood bench. The scene will come in the winter premiere (Season 4, Episode 14: “Who’s in the Box”), which sees Caleb leaving Rosewood for nearby Ravenswood. We can’t imagine that’s a fun conversation, no matter how noble Caleb’s yet-to-be-revealed reasons for departing may be.

We understand Marlene’s sentiment. Tyler has been a part of the PLL cast since Caleb first appeared in Season 1, Episode 14: “Careful What U Wish For” as the new tech-savvy foster kid in town. Since his introduction as a sarcastic stranger, he has gone to the rock of Hanna’s life and one of the people the Liars can depend on most. Off-screen, he has become an integral part of the cast and one of Ash’s BFFs. We’re sad to see him go, but excited for the actor to get new and challenging storylines of his own on Ravenswood.

What do you think is going down in Haleb’s farewell scene? Why do you think Caleb is leaving Rosewood? Sound off in the comments below!
