Recently we’ve spent some time examining clues that Alison (Sasha Pieterse) may have a twin on Pretty Little Liars. And in Season 3, Episode 6: “The Remains of the ‘A’,” (which aired on July 17), Jason (Drew Van Acker) made a comment that suggests Ali definitely did have a twin, and that Jason might be ready to share that information with others. 

Ever since the series began, clues that Alison (or her twin) is still alive and in Rosewood have been cropping up. The Little Liars’ hallucinations, which may or may not be real encounters with Alison, and the photo of Ali, Jason, and a girl who looks exactly like Ali in the Season 2 Halloween episode (Season 2, Episode 13: ”The First Secret”), are just a couple of the signs.

In “Remains of the ‘A’,” Mr. Hastings confronts Jason after he spots him having a secret talk with Spencer (Troian Bellisario). As all PLL fans know, Mr. Hastings is Jason’s real father, and Spencer and Jason are half-siblings. Mr. Hastings urges Jason to leave Spencer out of his search for Alison’s killer, saying, of Spencer, “She needs to find a way to put this behind her, the trial, her sister...”

But Jason interrupts him with, “Which sister exactly are you talking about? Because as it turns out, I had more than one.” Whoa. Could this be the most blatant indicator yet that Jason is ready to talk about Ali's twin, and his other sister?

Of course Jason could simply be referring to the recently revealed knowledge that both Spencer and Melissa (Torrey DeVitto) are his half-sisters. But something about the way he said it — forcefully and in an almost threatening way — makes us suspect that Jasonis ready to share. After all, publicly, Jason only ever had one sister — Alison — and he still hasn’t developed any kind of sisterly bond with Melissa (even if they once had a romantic one!).

Tell us your theories in the comments!

UPDATE: Thanks to commenters, we've changed the article to reflect the fact that there was a photo of Jason, Alison, and an identical blonde girl in the Season 2 Halloween episode. So Jason must have known that Alison has a twin. 

Catch an all-new episode of PLL on Tuesday, July 24 at 8 p.m. ET/PT on ABC Family.
