Many “Pretty Little Liars” fans are still in shock after the summer finale revealed that the beloved Ezra Fitz (Ian Harding) could be none other than “A” her—well I guess now its him—self.

While many were taken aback by this dramatic change of events, Harding wasn’t really too surprised.

“I'm not really shocked by anything on this show. When they told me I was like, ‘Oh, cool. Yeah. I can see that happening’,” he said in a recent interview with TVGuide.com. “It'd be weird if we found out that he's actually a shape-shifter or something like that.”

For those of you who thought Ezra’s creepy hobby would cause an immediate end to whatever he and Aria (Lucy Hale) have rediscovered, think again.

“I think their relationship is going to be a fun one to watch,” said Harding. “Because their whole dynamic for the past couple seasons has been Ezra kind of in the dark about everything that was going on in her life. Now, that's completely switched, because in whatever form their relationship takes from here on out, we are all going to know that Ezra has a secret that Aria is not aware of.”

What’s Harding’s advice for the Halloween Episode? Get ready to be frightened.

“It's going to read more of the thriller, and actually, some parts are downright scary,” he describes the special. “Some parts are horror film-esque.

Although Harding said it was “possible” Ezra’s anger was generated because he realized Aria was being hurt again, he does drop significant hints in the interview that just about confirm Ezra is really ‘A.’
