ABC Family’s hit teen drama Pretty Little Liars returns tonight! The devastating discovery that Toby (Keegan Allen) is part of team A will shake our favorite heroines to their core, especially Spencer (Troian Bellisario). In an interview with TV Guide, PLL executive producer Oliver Goldstick teases what’s in store for the four.
"This is a devastating season for Spencer," Goldstick says. "She comes from a family where you really can't trust what they say and no one is really honest and now she's [been betrayed] by the one person she gave all of her trust to, Toby." And although Spencer tries to warn her half-brother Jason (Drew Van Acker) about getting close to Mona, he too may turn on her (and look awfully suspicious by the end of the premiere). "The girls are kept guessing with Jason for a long time," Goldstick adds. "Something is revealed later on in the season that will clear up Jason a lot and what his motivation is, but for right now he's someone to be wary of."
