'Pretty Little Liars' season 7 spoilers: Uber A, dark knight may return on episode 10?

Fans of the American teen drama series "Pretty Little Liars" are all hyped up with the recent confirmation given by Marlene King, the show's executive producer. King recently revealed that a member of the cast who had been speculated to be A — before it came out that Cece Drake was the real big bad — would return and that it would be before "Pretty Little Liars" ends.

King responded to a fan's question on Twitter on whether Julian Morris would be back, saying, "Definitely season 7."

Wren Kingston, played by actor Julian Morris, will be coming back on the show. It will happen in the tenth episode of the present seventh-season run, entitled "The Darkest Knight."

Now followers of the show are speculating on who he could turn out to be. Some believe Wren could be Uber A or the dark knight pursuing the pretty little liars as shown in the flash forward scene.

The character last appeared in an episode in season 4. He was seen talking with someone on the phone at Radley. He shared that he had felt that Mona's (Janel Parrish) confession was somehow forced and went on to say that he had been surprised that even his almost-mother-in-law was in on it.

He ended the call by saying something which appears now to be very apt in the light of the possibility of him being the villain. Wren said that it only shows that nobody could really be trusted.

Is Wren who everyone thinks he is? Could he and Elliot Rollins (Huw Collins), who incidentally are both British, be long-lost siblings?

"Pretty Little Liars" season 7 returns with episode 3 on Tuesday, July 5, with "The Talented Mr. Rollins," followed by episode 4, "Hit and Run, Run, Run," on July 12, and episode 5, "Along Comes Mary," on July 19.
