The seventh episode of the "Pretty Little Liars" season 5 promises to be more exciting as Aria and Spencer will intensify their espionage techniques.

ABC Family, the network that houses PLL, released the official synopsis and spoilers of the next episode of the hit suspense series entitled "The Silence of E. Lamb".

The synopsis is as follows: "In the new episode 7 press release: Spencer and Aria will take their spying up a notch. Press release number 2: Aria and Spencer will go to great lengths to get answers, while Emily and Hanna are put in uncomfortable positions. Press release number 3: Aria is going to begin her volunteer work at Radley and will quickly get down to business, finding any answers she can about a patient of interest to the Liars."

However, Aria will also hit a slight bump along her way when she comes across with an aggressive patient, which could be the key that the liars were looking for. Spencer, on the other hand, will learn from Ezra's play book and she will borrow some of his spy equipment to take her spying a notch higher.

Meanwhile, Hanna will deal with Caleb's return. In the 100th episode of the series, Hanna ran into Caleb, which made her distracted ever since. There were speculations that Hanna will go into a love triangle with Caleb and her current boyfriend Travis, especially since her relationship with Travis is quite shaky.

Actor Tyler Blackburn, who plays Caleb, said that there will be a lot of interaction between Hanna and Caleb. The actor neither confirmed nor denied whether he and Hanna will get back together.

"We definitely interact together, so I think that will be pleasing to the viewers," Blackburn admitted to Hollywood Life, "but I'm not going to say whether or not they are making out again," he said.

"Pretty Little Liars" season 5, episode 7 will air on July 22, 7 PM on ABC Family.
