When we found out that (spoiler alert) CeCe Drake was the big bad "A" on "Pretty Little Liars," we were shocked. It's not that we didn't see it coming -- we'd always thought CeCe was suspicious -- but we definitely weren't expecting the complex storyline that followed.

By now, fans of the show probably know how the summer finale ended. (And if you don't, it's been almost a week, so what are you waiting for?) CeCe Drake (Vanessa Ray), aka Charlotte, who was born Charles DiLaurentis, was revealed as the girls' vicious tormentor. People all over the Twitterverse freaked out , telling showruner I. Marlene King that she'd ruined their lives. Others called King out for the transgender storyline, saying it was "hackneyed" and "harmful."

But King stuck by the show's big reveal and defended the writing .

"We certainly did not jump on the bandwagon," she told Entertainment Tonight. "We definitely came up with this idea three and a half years ago. I mean, it's been a long time in the works and if you go back and you watch the CeCe episodes -- because I went back and rewatched every single one, and reread all the scripts to make sure I didn't make any mistakes in this finale -- we've told you she is 'A' so many times."
