For Pretty Little Liars dvd fans who felt last season's big reveal wasn't a shock, executive producer Marlene King promises that this Tuesday's finale will make up for it tenfold.
"Honestly, people's jaws will hit the floor," King tells TVGuide.com. "For people who felt like [Mona being A] wasn't the big twist they were looking for, they're getting their big twist tomorrow. And the fact that it's two massive, mind-blowing twists, fans will be so shocked and satisfied by this episode. "
