Cliffhangers and perverse secrets are coming to Pretty Little Liars on tonight's season finale.

But will any involve Ezra and Aria? The relationship between these two characters took a pair of hits last week, as a police officer saw Aria leave Ezra's apartment and someone took the key Aria uses to get into Ezra's place.

"I think it's going to make for a good surprise because the cops are there, but for what reason is still a mystery," Ian Harding teased to TV Guide. "Whoever lifted up that mat is also going to be surprising."

The actor also says that Jackie, Ezra's ex, could be "sticking around for awhile." What else can he reveal about the season finale?

"People are going to be angry at Ezra because there's going to be some words that were not spoken to Aria that she's going to be pretty [angry] about. There's a picture online right now of me from the season finale (ABOVE) and if you look closely I'm in Aria's bedroom, which I've obviously never been in before. I'll leave that for the viewers to salivate over. There's also a very awesome moment in a bell tower."

How intriguing. Return to TV Fanatic soon after this episode ends for a details recap and review.
