Liars fans, we’re hours away from what will likely be a finale that angers fans in the best possible way. We know there will be a huge moment, a gasp, and a frustrating fade to black, leaving us knee-deep in mystery until June. The good news? There’s so much drama to be had before then.

In tonight’s finale, (as teased in Friday’s Spoiler Room) there will be a big secret revealed that will change the direction of the mystery, and tie up a few lingering plotlines. For Spencer Hastings (Troian Bellisario), that means dealing with the host of problems before her. “She’s falling through the floor and hitting rock bottom as far as being investigated by the police, being ostracized by her family, losing her connection with her sister, and not [being] sure [of] who she can trust,” Bellisario tells EW. “And she’s the prime suspect in the murder of her best friend, and she knows she has a really good reason to have done it. I personally think Spencer hasn’t. But she had the motivation, the connection, and the rage toward Ali, and now that’s all coming back and biting her in the butt.”

And come season 2, Bellisario expects more to come back and haunt Spencer, namely the events from the night of Ali’s disappearance. “You got to see this season a little bit of what happened between Spencer and Ali that night, and to me, that’s a storyline I’d like to see. I don’t know where [the writers are] going to go with anything, but I would love to find out that night,” she says.

Whatever may come, the actress says she’s most happy that Spencer now has a new (and forbidden) support system in Toby, her former nemesis of sorts. “What’s really great about the show is that even though she’s falling down the rabbit hole in the sense, she’s also falling in love, and finding a true connection with somebody,” she says. “For the first time, somebody is actually saying, ‘What do you want?’ It’s really beautiful. It’s fun for me to play the dichotomy of having some of the best moments of your life come immediately after or before some of the worst.” And what, exactly, is “the worst”? Our guess is that we’ll find out tonight.
