Welcome home, brother!  “Pretty Little Liars” fans received a big shock during episode 6 when it was revealed that Charles DiLaurentis wasn’t really dead. And if that wasn’t spooky enough, Kenneth DiLaurentis (Jim Abele) found a lovely card from his estranged son: “Coming home for my birthday. You should plan a party to die for. Just you. Love, Charles.” Pack your bags … it sounds like it’s time to leave Rosewood in episode 7!

Tuesday night’s episode concluded with Kenneth digging up Charles’ grave to look for a body. While viewers didn’t see what he found buried, the synopsis for episode 7, titled “O Brother, Where Art Thou,” makes it sound like reality finally hit the DiLaurentis patriarch. According to the synopsis, Kenneth wants Alison (Sasha Pieterse) and Jason (Drew Van Acker) to get out of town and hide. Alison might be on board, but Jason has no plans on running away from his older brother. “Jason sees this as an opportunity to finally validate all of the early childhood memories he has of ‘Charlie,’” the synopsis teases.

Like the DiLaurentis family, the Liars are unsure about what to do as well. Spencer (Troian Bellisario) and Hanna (Ashley Benson) are ready to do whatever they can to capture Charles. However, Emily (Shay Mitchell) and Aria (Lucy Hale) feel the exact opposite. The episode description reveals that the two teens “want to stay as far from his as possible.”

But of course there is a catch. The synopsis asks a juicy question: What if this is “just another of ‘A’s’ traps?” And if it is a trap … who is “A” trying to catch?

Of course, that’s not all the drama that “Pretty Little Liars” fans can catch in episode 7. Mike (Cody Christian) is trying to reconnect with Mona (Janel Parrish) – but she wants nothing to do with him. The synopsis explains that she’s shutting her ex-boyfriend out. But why? Possibly to protect him from “A’s” wrath … or even police questioning. Meanwhile, Hanna gets “an unwelcomed surprise.”

Episode 7 of “Pretty Little Liars” Season 6 airs on ABC Family on Tuesday, July 21 at 8 p.m. EDT. Tweet your thoughts and theories about “O Brother, Where Art Though” to @AmandaTVScoop.
