When discussing the greatest communique ever sent by “A” in Pretty Little Liars history, arguably nothing will top the original text sent to all four girls by the mysterious cyberstalker in the pilot: “I’m still here bitches, and I know everything.” Concise, simple, and utterly terrifying. But with each passing season, A’s messages became increasingly more complex, ranging in style from the mind of a cheeky teenager to a fully fledged psychopath. The delivery, too, became more nuanced — what began as simple texts via cell phones developed into messages in the form of newspaper classifieds, balloons, wind-up dolls, Magic 8 balls, even human-teeth necklaces. (The A team, clearly, had a lot of spare time on their hands.) Before the seventh season premieres Tuesday night, take a trip down memory lane and relive some of the most shockingly memorable — and just plain amusing — messages A has sent Rosewood residents throughout PLL’s history.
