[Warning: This story contains spoilers from the season-five finale of ABC Family's Pretty Little Liars.]

Pretty Little Liars delivered plenty of jolts in its season-five finale — and even some electricity. 

Last week, Alison (Sasha Pieterse) was found guilty of first-degree murder in Mona's (Janel Parrish) death, with Emily (Shay Mitchell), Aria (Lucy Hale) and Spencer (Troian Bellisario) all getting hauled off to the slammer to join Hanna (Ashley Benson). 

The finale began with the Liars on their way to jail when the police van was hijacked. The next thing the girls knew, they were waking up in a giant doll house with replicas of their bedrooms. "A" really needs to get over this unhealthy fixation on dolls.

They saw someone playing piano with blonde hair and a mask, and it turns out to be — gasp! — Mona, who's stunningly still alive. However, Mona's convinced that her name is Ali, and she's even wearing Ali's yellow top. 

Mona told the girls to play Mystery Dream Date to pick their prom dates, which no one was happy about. But during a sudden power outage, Mona gathered the girls to let them know she really is Mona, and that she has just been playing along so "A" won't hurt her. 

The girls stayed in the dollhouse, where Spencer had a vision of the name "Charles" spelled out in blocks. Meanwhile, Mona received a gas mask and a note saying she is A's favorite.

The Liars are forced to plan their prom, including outdated music and couple arrangements, until Spencer managed to figure out how to rig the electronics so they can kill the power. Thank goodness for Spencer.

On the outside world, Toby (Keegan Allen), Ezra (Ian Harding) and Caleb (Tyler Blackburn) teamed up to track the van before telling Spencer's parents that "A" is back. The police helped them find A's lair, which creepily contained footage of the girls in their dollhouse. 

Back in the dollhouse, Spencer was watching a projector playing home-video footage of twin boys with Ali's mom when a man in a masquerade mask walked up behind her. Mona entered the room to say that "A" has a soul, and suddenly the guy was gone. Nice timing, Mona!

The five gals think they've escaped through the yard but realize they're surrounded by an electric fence. What is this, Jurassic Park? Sadly, Charles' face was never revealed, although the #CharlesIsA hashtag confirmed that the mystery dude is in fact the nefarious villain. 

So could this mean "Charles" is Jason's (Drew Van Acker) twin brother? Or could "Charles" be an alias for one of the other men from the show, including Lucas (Brendan Robinson) or Wren (Julian Morris)? What do you think of Mona still living and breathing? And are you hoping to never see that yellow top again? Let us know in the comments!
