When "A" was finally unmasked on "Pretty Little Liars" after six, long seasons, Julian Morris felt like he could finally breath a sigh of relief.

"I feel like that could be a lyric to a song: 'It wasn't Wren,'" Morris told MTV News in New York City, where he was promoting his Amazon series "Hand of God."

Wren Kingston wasn't "A," but that doesn't mean his "PLL" story is over. Expect the enigmatic Doc to make a trip across the pond before the show wraps its seventh -- and maybe final -- season.

"I've promised Marlene [King] that I will return at some point in the season to resolve my character -- for myself and also for the fans," the actor said. "So as long as she's still up for that, I will come back in some capacity. It would be cool."

Julian Morris as Wren on "Pretty Little Liars."

We last saw Wren in season 4, coloring in that creepy sketch he showed to Mona at Radley -- a sketch of a woman, in a red coat, with her family in front of a barn. Wren abruptly moved to England later in the season.

"What I would love is some resolution with Spencer," the 32-year-old said. "I always thought -- and this is how I played it -- that he was in love with and loved Spencer, so it would be great to resolve that."

"Although, obviously, she's now with Toby, so I don't know how he'd feel about that," Morris added.

Given the five-year time jump in season 6B, it's entirely possible that Spencer and Toby might not even be together next season. So, Wren might actually have a chance! That being said, we're still not sure Wren can be trusted. After all, we know Ali and the Liars are running from "him" when "PLL" returns in 2016 -- so Wren isn't in the clear just yet.

"I know there was some disappointment with the reveal at the end of that episode," he said. "However, it's not the final season. The season now is the final chapter, and I think that's going to be the big reveal. So it could still be Wren."

That smirk is NOT to be trusted.

For now, fans will have to get their fix of the dreamy Brit on the new Amazon series "Hand of God," which the actor described as an "extension" of "Pretty Little Liars."

"In a way that I grew up on 'Pretty Little Liars,' I think a lot of the fans have as well," Morris said. "So for me, it was about looking for a challenge of a character that was morally conflicted, that was more of challenge that I've been given before but equally as fun. And it is ultimately a whodunnit. It's not 'A' this time around -- it's something a little darker."

After a few seasons of playing smaller, albeit interesting parts on shows like "PLL" and "Once Upon a Time," Morris found himself in a bit of a rut. He was doing a job he enjoyed, with people he loved, but creatively, he wanted something more.

"I had been [on] 'PLL' and 'Once Upon a Time' and some other stuff, and I was really enjoying it," he said. "I was loving everyone that I was working with. But I realized that I was settling into what I knew I could do, and I started to think about why I got into acting in the first place. It was because of the directors, people like Marc Forster ['Monster's Ball'], and the challenge that it presented. So I made a break with 'PLL' and 'Once Upon a Time.' And I felt like I needed to do that to give myself the opportunity to give myself these other challenges."

Julian Morris guest starred as science teacher Ryan on "New Girl."

Then, came the opportunity to star in an indie film called "Kelly + Victor," a story about an intense, transgressive love affair.

"I'm so proud of that film," he said, smiling. "The director had never directed before, at least not a drama, and he ended up winning the BAFTA for it, for the film, and it's one of the things I'm most proud of."

With his mojo restored, Morris took a chance on a pilot called "Hand of God." Soon after, he booked a guest starring role on Fox's "New Girl," alongside star Zooey Deschanel. That presented a new kind of challenge for the actor.

"I was like, 'Oh, s--t.' Because it was a comedy, and I don't do comedy!" the actor said. "My first day, I learnt my lines -- way more than I normally ever learn them -- and then I arrived in the trailer and they do this thing called alt lines, where they have all these alternatives to what you're saying, and I was like, 'I have to learn this, too?' But then you just play and have fun. It was just a dream. I had never done anything like that before."

While the experience couldn't have been any more amazing for the actor -- who had to say goodbye to "New Girl" once his Amazon pilot was picked up -- he does have one, tiny gripe. Ryan, like Wren, was sent back to the U.K., instead of someplace, you know, warmer.

"It's like, 'Guys, I'm English. Can we think of something else? Also, can I move to Spain? Be on a beach in Hawaii? Go to surf school?'" Morris said. "But I just get sent home -- to the rain. It happens every time."
