There are a lot of different monikers thrown around on Pretty Little Liars: “A,” Red Coat, Board Shorts, etc. However, right now, we’re most interested in that last one, the nickname the Liars have for the older guy Alison (Sasha Pieterse) had a fling with on Cape May the summer before her disappearance. We now know that Ezra (Ian Harding) is after Ali, but is he Board Shorts? We’ll find out soon enough.

Good news, PLL fans! The answer is coming soon. Sasha said that we’ll definitely discover if Board Shorts and Ezra are the same person in Season 4B, and that the reveal is one of her favorite moments ever: "I was just super-excited and thrilled in the way that they unraveled and tied in and I think it's brilliant. It's just absolutely brilliant," Sasha told E! Online about the upcoming Ezra vs. Board Shorts reveal.

She continued: "I think the fans are going to be like 'Really? How did we not think of that?!' It's awesome, it really is. It's actually one of my favorite scenes in one of my favorite episodes, so you'll appreciate that one."

That’s high praise from someone who gets to be a part of so many epic PLL scenes. We’re not sure what we haven’t thought of when it comes to the “Is Ezra Board Shorts?” debate, but we’ll wrack our brains for theories. After all, Season 4B is still a few months away…
