With season 4 of "Pretty Little Liars" growing ever more sinister, where does Aria's new love interest introduced in yesterday's episode "Turn of the Shoe" fit into the picture?

In last night's episode, Aria arrives at a dojo frequented by Holden Strauss, an old friend of Aria's who was introduced in season two. If fans recall, Holden was a potential love interest of Aria who eventually revealed his hobby of tournament fighting despite a heart condition that required medication.

The more interesting point is that like most of the characters on "Pretty Little Liars," Holden could be working for 'A' in some way based on a season 3 episode.

This makes Jake, the teacher at the dojo and Holden's acquaintance, an interesting addition to the show, especially since Aria kisses him in "Turn of the Show."

Jake is played by Ryan Guzman, an actor famous for his dancing skills in movies like "Step Up Revolution" and the reality dance show "All the Right Moves."

Check out an interview with Guzman during the "So You Think You Can Dance" finale below:

Will we see a lot more of Jake in the future?

"Pretty Little Liars" also recently revealed another new potentially recurring character, a mysterious mask maker who could have made the Allison mask, reports The Hollywood Reporter.

Check out the sneak peek featuring him below:

The sculptor is named Hector Lime and is described as a "Tim Burton-ish character who makes props and statues for horror movies" by Kristin Dos Santos of E! Online. Hector will be introduced in the next episode on June 25.

The third episode of the season, titled "Cat's Cradle," will also start reportedly introduce the transition to ABC Family's "Pretty Little Liars" spinoff, "Ravenwood," when Spencer and Toby go to the town for clues.

With so many exciting developments coming up, don't forget to tune in to "Pretty Little Liars" next Tuesday.
