We knew it was coming. In tonight’s Pretty Little Liars Season 4 summer finale, we would finally get the answer to the question that has been plaguing us since the very first episode all those years ago. Is Ali (Sasha Pieterse)?

During August 27’s Season 4, Episode 12: “Now You See Me, Now You Don’t,” we finally got our answer. Ali is, in fact, alive. This entire show has been built around the trauma of life in Rosewood after Ali’s murder... when the sneaky little blonde has actually been alive all along.

The Little Liars made this discovery when they raided “A”’s lair... and made the discovery that “A” and Ali’s jilted lover, “Board Shorts,” are actually the same person. Later, Mrs. Grunwald gave the girls all the details. She revealed how she came over to Ali’s house that night to find her buried alive, pulled her out of the ground, and drove her to the hospital.

But then Ali disappeared without a word, and Mrs. Grunwald hasn’t seen her since. So can we really be sure that she’s still alive at all? Unfortunately, no.

Sasha told E! Online that fans will see a part of the story in the summer finale, but they won’t know the whole truth until the Season 4 Halloween episode on October 22. So yes: for now, Ali very much appears to be alive. But things aren’t always as they seem. We still have to wait another month until we can find out for sure.
