Fans will not want to miss the DiLaurentis family reunion when episode 7 of “Pretty Little Liars” airs on Tuesday. The upcoming installment, titled, “O Brother, Where Art Thou,” is gearing up to be one of the most chilling episodes of Season 6 – and viewers don’t have to wait until July 21 to get a look at the action.

ABC Family has released three sneak peek videos for episode 7. Watch them all below:

Sneak Peek 1

Daddy DiLaurentis has been keeping too many secrets! The first sneak peek video shows Kenneth (Jim Abele) throwing a suitcase into the trunk of his car before getting a frightened and confused Alison (Sasha Pieterse) into the passengers seat. The car ride starts off in silence, but Alison soon begins to question what’s going on. Unfortunately, her dad’s not willing to talk. He simply reassures her that he’s taking her “someplace safe.” But Alison’s fears only grow when she reads the birthday card that her “dead” brother Charles sent their father.
“He’s alive and he’s coming for us, isn’t he?” she asks her father.

Sneak Peek 2

Welcome home, Toby (Keegan Allen)! Spencer’s (Troian Bellisario) boyfriend finally returns from an out of town police seminar, but the timing is off for the couple. Spencer’s on her way out when he shows up – and she can’t cancel her plans. Of course that makes Toby suspicious. And it doesn’t help that Spencer receives a text from Aria (Lucy Hale) asking her where she is. Toby immediately thinks that it has something to do with “A,” and warns Spencer that they can’t keep secrets from each other. However, Spencer insists that Aria is simply helping her write her valedictorian speech. Is she telling the truth? Or did Spencer just lie to Toby?

Sneak Peek 3

Poor Mike (Cody Christian) is getting the cold shoulder from his ex-girlfriend, Mona (Janel Parrish). “Pretty Little Liars” fans will remember that Mike was all torn up when he thought that Mona was murdered. Now she’s back … but not interested in rekindling things with her former flame. In the sneak peek video, Mike reveals to Aria that Mona’s been dodging his calls and that he hasn’t seen or talked to her since she was rescued from the Dollhouse. Mike initially thinks that his sister has something to do with the silence, but Aria breaks the news to him that she never told Mona not to talk to him.

As we previously reported, episode 7 will find everyone on edge after Charles claims he’s coming home for his birthday. Kenneth wants to get his son and daughter out of Rosewood, but Jason (Drew van Acker) wants to stay and come face-to-face with his brother. Like the DiLaurentis family, the Liars are also split about what to do. Spencer and Hanna (Ashley Benson) want to try and catch Charles, while Emily (Shay Mitchell) and Aria want to “stay as far from him as possible.” But will Charles even surface? Or is he just playing another game? “Pretty Little Liars” fans will have to wait and see!

Episode 7, “O Brother, Where Art Thou,” will air on ABC Family on Tuesday, July 21 at 8 p.m. EDT.
