The Pretty Little Liars cast and crew wrapped up the filming for Season 3 yesterday (November 15). And by "yesterday," we actually mean "the wee hours of today," as we learned when the cast took to Twitter to talk about their 20 hour day (!).

Why did it take so long to film? Showrunner Marlene King has a very good answer.

"What is it about a finale that keeps us up so late?" she tweeted. "Oh yeah, it's a kick ass, mind blowing, crazy as hell epic story."

In the same vein, Keegan Allen (Toby Cavanaugh) recently told us that the finale will "shock everyone in the world." We can't wait to have our minds blown to bits again!
