Toby Punches Caleb on Tonight's 'Pretty Little Liars'

Aria (Lucy Hale) looks a tad worried in this still from tonight’s all-new episode of Pretty Little Liars.

In “Burn This,” after the stalker nearly killed Emily (Shay Mitchell), the Liars begin to take the threats more seriously and attempt to keep their mouths shut to prevent any further harm.

Caleb (Tyler Blackburn) must deal with the collateral damage of taking the blame for the leak about Yvonne; Spencer (Troian Bellisario) tries to comfort him and get him to tell the truth.

Emily goes on a mission to track down who came after her. Aria and Ezra (Ian Harding) move forward with the novel.

Meanwhile, Hanna (Ashley Benson) avoids dealing with her personal life.

Pretty Little Liars airs TONIGHT, March 1 @ 8PM on Freeform!
