With the cancellation of Ravenswood, comes the return of our beloved Tyler Blackburn (Caleb) to Pretty Little Liars. Caleb will be returning in Season 5, Episode 5 — which also happens to be the 100th episode — to a very changed Rosewood: Alison (Sasha Pieterse) will officially be back in the land of the living. How will Caleb and Ali react to one another? Pretty Little Liars executive producer Marlene King teased their meeting to The Hollywood Reporter.

"Tyler, Sasha, and I were talking about this — that Alison and Caleb have never met. That's a pairing we've never seen,” said Marlene. “He comes in knowing about this persona, this mythical figure Alison, and now he gets to meet her for real. That's going to be chemistry we get to see."

Hold it… chemistry?! We don’t like that word attached to Caleb and anyone other than Hanna. OK, fine, maybe they’ll just make excellent bridge partners — or maybe Ali and Caleb will realize they have more in common than they thought. After all, they’ve both hit their heads and almost died (or temporarily died, in the case of Caleb). With Hanna presumably cross with Caleb for leaving and starting up a new romance with the dashing Travis, where does that leave Caleb upon his return? We’re not trying to be alarmist here, but we know that Alison’s return will cause some trouble between the Liars and their significant others. Will one of those problems be between Haleb?

Do you think Alison and Caleb will get along? Sound off in the comments below!
