With the fifth season of ‘Pretty Little Liars’ getting under way, theories and spoilers are popping up all over — and there are some good ones to share!

Warning: Lots of spoilers below for the entire fifth season, so proceed with caution.

Tammin Sursok (Jenna Marshall) just confirmed that the twin theory, despite previous reports, is true! “Someone has a twin sister,” she revealed to The Daily Edition. “I can’t give too much away, or then I’m going to have to kill you!”

That’s plenty to get our gears grinding, Tammin. The show creators previously denied that Alison has a twin, despite her having a twin in the ‘Pretty Little Liars’ book series by Sara Shepard. If not Ali, then who?

The actress also confirmed that Shana is not actually ‘A’ — which we all could’ve guessed by now. “We find out who ‘A’ is, and then it’s not really ‘A,’” she shared. That definitely sounds like it could be Shana’s arc!

As far as the Liars go, there are rumors circulating that Spencer could be facing a relapse in her Adderall addiction. “There’s a big hump [Spencer and Toby] have to get over, which is that it wasn’t really her choice to get off the drugs, even though now she’s doing a lot better,” ‘PLL’ actress Troian Bellisario told OK Magazine. Poor Spencer — and Toby! Hopefully their relationship can survive another bump in the road.

What do you think, ‘PLL’ fans + PopCrushers? Who has a secret twin? Do you think Spencer will relapse?
