Surprisingly, the death of 'A'/Shana came at the hands of the series' most innocent Liar. Now that her elusive tormentor appears to be dead, how will Aria (Lucy Hale) reconcile her new, hopefully peaceful (yeah right), life with the crime she just committed?

"It affects her tremendously," explained executive producer Marlene King, according to TV Line. "One of the questions the girls have always asked is 'Why did Ali pick us? Why were we the team she put together to be her friends?' And those answers will come. One of the reasons she picked Aria is because she's so compassionate, and now that - as you say - she's tasted her first kill, it will affect her dramatically. And traumatically."

Meanwhile, the apparent demise of 'A' has left viewers wondering just how the Pretty Little Liars writers will fill the next three seasons. According to King, the reveal of 'A' was penned with the possibility of season 6 and 7 in mind.

"[It] was a very conscious decision to shake it up with a premiere that felt like nothing we'd ever done before," King told TV Line. "Along with the news of Season 6 and 7, I think some fans got nervous that it meant we'd keep dragging things out, so we wanted to assure them that the show is going to stay really hot."
