'Pretty Little Liars' Season 7 Summer Finale: The Episode's Most Shocking Moments

— -- Was that the best episode ever ... or was that the best episode ever?

On last night’s “Pretty Little Liars” summer finale, Spencer Hastings, Aria Montgomery, Hanna Marin, Emily Fields and Alison DiLaurentis found themselves in one of their most perilous situations ever.

Locked inside a creepy former school for the blind, the girls had nowhere to escape from Jenna Marshall and Noel Kahn, who set out to kill them with a gun and an ax. And one of the Pretty Little Liars may not have made it out alive.

But before those nail-biting moments, fans got to see one of their favorite couples reconnect, while others said what might have been a final goodbye.

To learn who survived, who is A.D. and how their story will finally end, we’ll have to wait until April 2017 season premiere, which will be the show’s last ever.

If you’ve still got all the feels about last night’s finale and don’t know what you’re going to when the show ends, just remember happier times -- like last night’s Haleb kiss!

Check out that moment and the episode's other most shocking moments below:

1. Alison might be pregnant?

Alison revealed to Emily that she thinks she’s pregnant and that Archer Dunhill, aka Dr. Elliot Rollins, might be the father. Emily and Alison reconnect and end up kissing. But Emily’s ex-girlfriend Paige McCullers thinks it’s just another ploy by Alison to keep Emily and Paige apart.

2. #HalebForever

Hanna and her ex-boyfriend Caleb Rivers finally realize they are meant to be and spend a pretty steamy night together.

3. Spencer and Toby kiss.

Spencer’s ex-boyfriend Toby Cavanaugh sold the house he built for her and made plans to move away with his fiancée, Yvonne Phillips. Spencer visits him to say goodbye, and in a tear-jerking moment, she asks him for one last kiss.

4. Nicole is alive.

Aria and her fiancé Ezra Fitz were going to elope to Italy, when news broke that Ezra's girlfriend Nicole Gordon might still be alive. Nicole was thought to be kidnapped by rebels in Colombia and found alive, so Ezra went to Colombia to find out. He called Aria to say he learned that she was not among those rescued and was returning home. But after Ezra never arrived in Rosewood, Aria saw him on TV hugging Nicole, who was indeed alive.

5. Jenna and Noel try to kill the Liars.

Armed with a gun, Jenna pursues Spencer, Alison and Aria through the dark. Meanwhile, Emily and Hanna are cornered by Noel who has an ax. While fighting Noel off, Emily and Hanna watch as Noel is decapitated by his own ax. In the ensuing frenzy, Jenna shoots at the girls, who all manage to run away, except Spencer.

6. Spencer is Mary Drake’s daughter.

Before Jenna could kill Spencer, Mary Drake stops her. The other girls arrive just in time for Mary to reveal that she is Spencer’s mother. This means that Spencer is Charlotte DiLaurentis’ twin, and not Noel, despite the girls’ previous theories.

7. Are Spencer, Toby and Yvonne dead?

After Mary reveals she is Spencer’s mom, Spencer closes her eyes and appears to die. We then learn that Toby and Yvonne got in a car crash and also appear to be dead.

8. We still don’t know who A.D. is.

Noel is dead, and therefore can’t be A.D., the mysterious and unnamed figure who is torturing the Liars. Jenna is saved by A.D., so it can’t be her. Could it be Sydney Driscoll, who made a surprise appearance last night pretending to be Jenna? Viewers will have to wait until next year for the final answers and #PLLEndGame.
