Before writing the midseason finale, "Game Over, Charles," King "went back and watched all of Cece's scene of the show, saying, "There are clues that are dropped so many times, like going back I was like we are so bold. I can't believe we are doing this!"
When we chatted with King after the season five finale, which revealed A's name was Charles DiLaurentis, she spilled that there were two other candidates up for the title of the show's Big Bad before she decided on Cece back in season three.
So is she ready to spill who the other two potential A's were? Nope! "I feel like that story may come up in future episodes, but not as A but as a villain," King teased.
