SPOILER ALERT: Stop reading now if you wish to remain in the dark about a key development on Pretty Little Liars Season 5 Episode 12.
Because ABC Family was not kidding for once. This episode deserved to be dubbed a "Fatal Finale."
Mona Vanderwaal is dead.
The heretofore evil character, believed at one point in the past to be A, was brutally murdered at her home by a mysterious (blonde?) assailant.
Before she died, however, Mona got through to Aria to tell her that Alison lured Bethany to Rosewood in the first place. Yes, our suspicions about Ali and her role in her own disappearance are stronger than ever.
