After four seasons, countless clues, and plenty of misdirects, we finally learned the identity of “A” during August 27’s Pretty Little Liars Season 4 summer finale, Episode 13: “Now You See Me, Now You Don’t.”

That’s not all, though. A very central character to the “A” story met her untimely demise, taking with her what was perhaps the Little Liars’ only chance to uncover some of the mysteries behind Ali’s (Sasha Pieterse) death.

Well, make that Ali’s supposed death. Nothing is for certain quite yet, but after watching the episode it seems entirely possible that Ali might not be dead after all.

Obviously, the summer finale is an episode not to be missed. So if you did have something more important to do on Tuesday night than watch PLL — Question: What was it, exactly? We can’t imagine anything more important — there’s still hope yet. The episode is available to watch online.

We know: Insert huge sigh of relief here.

Relieve every shocking twist from the summer finale by watching the full episode again. If you missed out on any details the first time around, this is the perfect chance to get caught up. Why not watch it again? You never know what you’ll pick up on the second time.

The full episode is available on Hulu, and we’ve included it below for your viewing pleasure. Yes, we are amAzing. You’re welcome.

Catch the next episode of Pretty Little Liars — Season 4’s Halloween episode — on Tuesday, October 22, 2013 at 8 p.m. ET/PT on ABC Family.
