Aside from last week's shocking episode ending with Sara Harvey (Dre Davis) found dead in a hotel bathtub, that show also featured Ezra (Ian Harding) and Aria's (Lucy Hale) surprise engagement as well as Ali DiLaurentis (Sasha Pieterse) finding herself once again in danger. This Tuesday's episode 7, "Original G'A'ngsters" will likely serve up plenty more plot twist, surprise turns and more.

According to the synopsis for episode 7, published on the official PLL website...

...a lot is expected to go down!

Starting off with Ali's brother Jason DiLaurentis (Drew Van Acker), who returns to Rosewood in a bid to help keep his little sister safe from their aunt Mary Drake (Andrea Parker). He is serious about his sister's safe-keeping, it seems, as a promo for the episode shows him telling Drake sternly to "get the hell off my property."

Ali herself seems the only character on the TV show who has opened up to the idea of trusting Drake after conversations between the two in last week's episode. Although initially suspicious of her aunt, Ali seems to give her the benefit of the doubt after Drake shares secret stories from her past with her niece.

However, in addition to Jason's return to protect Ali and his threats toward his aunt demonstrating an illicit distrust, the rest of the Liars have also been suspicious of Ali's aunt since she first showed up in Rosewood.

The Liars may tap into new information and secrets that Ali's aunt and mother could be hiding, with the synopsis mentioning a certain discovery about the DiLaurentis family leading them "to a storm cellar full of clues." What might the girls uncover in the cellar? Details on Mary and Mrs. DiLaurentis' past relationship? Clues about Charlotte's life that have yet to be uncovered? This mystery is likely to be uncovered during Tuesday night's episode.

Meanwhile, we're also told that Ezra gets a call about someone from his past that could change his course. This little tidbit has viewers guessing that the call may be regarding his ex-girlfriend Nicole (Rebecca Breeds), who is believed dead.

Meanwhile, Noel Kahn (Brent Daugherty) becomes the latest Uber A suspect as the girls continue to receive threats from their stalker.

Aside from featuring Jason's threat to Mary Drake, the promo for Episode 7 features a whole bunch of other PLL drama to be featured this week. In this clip we see the Liars apparently stuck inside a car that is rumored to be strapped with a bomb, the FBI showing up in town to question one (or all?) of the Liars, and Spencer (Troian Dellisorro) warning Toby (Keegan Allen) about his safety.

The episode airs on Freeform Tuesday Aug. 9 at 8:00 p.m. EST. It can also watched streaming live here.

Looking forward to next week's show (episode 8), "Exes and OMGs," TV Guide offers a summation of the following events that are expected to take place (Warning: Spoiler Alert!)

Emily (Shay Mitchell) is up for a position as swim coach at Rosewood High, but will be going up against her ex-girlfriend Paige (Lindsey Shaw), who is also in the running for the position.

Also: Hanna (Ashley Benson) has a vision that the girls are in danger; the Liars locate the doctor who delivered Mary Drake's baby; and lastly, Ali returns to work.

"Exes and OMGs" is scheduled to air on Freeform on Tuesday Aug. 16 at 8:00 p.m. EST and is one of just a few episodes left until the season finale! Be sure to check back with us next week, when we'll have available additional information, details and possible spoilers on Season 7, Episode 8.
