Pretty Little Liars' Caleb Rivers won't be falling into any of Alison's traps when he returns to Rosewood.

Will Haleb Pick Up Where They Left Off On 'Pretty Little Liars'?

Home from his stint in Ravenswood, Caleb (Tyler Blackburn) will soon meet Alison (Sasha Pieterse) for the first time. It's safe to say the teen is rather underwhelmed by the allegedly deceased character.

Caleb will have his grand homecoming in the series' 100th episode, "Miss Me x 100," and his initial reaction is to mind his own business. Unfortunately for him, his relationship with Hanna (Ashley Benson) will inevitably drag him into the fray whether he likes it or not.

"He doesn't get too involved in the Alison drama at first," Blackburn revealed to TV Line. "But then he speaks up, and he's just like, 'This girl is a liar.'"

Well, that boy is certainly astute. Lets hope Caleb doesn't fall into Alison's every growing web of lies. As Hanna, Emily, Aria, Spencer have learned, it's a web that's nearly impossible to climb out of.

Also in "Miss Me x 100," Alison will make her grand return to school and her attempts to make up for her past behavior won't quite go to plan.
