Alison is still alive. Leaving out the twin theory, and assuming that the murdered girl is not Alison, it’s plausible that all of the dreams, hallucinations, and visions of Alison that Emily and Spencer have had were not just dreams. What if they were real? Sasha has said in the past that Alison protects the Little Liars. Maybe she’s kept them out of harm’s way this whole time.
Alison is related to the Hastings, too. Jason (Drew Van Acker) revealed that his real father is Mr. Hastings. Somehow, Alison found out about this, but how? And if both families were able to keep Jason’s real parentage a secret for so long, who’s to say they weren’t keeping Alison’s real background a secret too? Remember: we know practically nothing about Alison’s father, and for a show so involved with father-daughter relationships, that seems like a big void worth exploring.
Alison is either the Black Swan or the blonde in the red dress from the masquerade party. With her Vivian Darkbloom wig, she could have possibly been the Black Swan who ran away from the girls at the ball. With her blonde hair, she could be the blonde who stopped by the ball, and was also seen in the last shot of the Season 2 finale as Maya’s body was wheeled away.
