The big reveal on Pretty Little Liars that Toby (Keegan Allen) is on the “A” team affects multiple people and storylines in Rosewood. But perhaps the person with the most to lose is Spencer (Troian Bellisario). As of now, Spencer fully trusts Toby, loves him, and even lost her virginity to him on the same day he was planning on framing her and the rest of the Liars for stealing Alison’s (Sasha Pieterse) dead body.

For someone as emotionally fragile as Spencer, finding out that the only person she’s been able to count on is actually the only person she never should have trusted in the first place will have some major effects on her life and state of mind. Here are a few of the biggest.

Her trust issues. Spencer already has trust issues stemming from her immediate family. Her mom secretly covered up her sister’s miscarriage and lied to Spencer about it. Melissa (Torrey DeVitto) had a secret connection to the NAT club, was in Alison’s bedroom the night she died, showed up to the Masquerade Ball as the Black Swan, and hid her relationship with Garrett (Yani Gellman) behind Spencer’s back. Then there’s her dad, who kept her half-brother Jason (Drew Van Acker) a secret from her all her life. To say that discovering Toby’s deceit might be the straw that breaks the stressed-out camel’s back is an understatement.

Her latent feelings for Wren. Spencer has been attracted to Wren (Julian Morris) (and he to her) since the first day she met him. But his off-limits status as Melissa’s fiance kept them apart at first. Then, her relationship with Toby got in the way. We doubt the whole Wrenna incident will have much of an effect on Wrencer (especially since Haleb will be “strong” in the second half ofSeason 3), but finding out about Toby might push Spencer to finally go for the gorgeous and charming doctor.  

Her wild side. Speaking of that hot doctor, remember the night when Spencer got wasted at a bar, only to wind up writhing around on Wren’s couch and sleeping over? He didn’t succumb to her advances back then because he knew she loved Toby, but what happens when Spencer’s single? Also, for anyone who thought Emily (Shay Mitchell) was the only Liar with a drinking problem, Spencer’s drunk side wasn’t pretty. What if Spencer goes back to the bar to escape?

Her vengeance. Spencer is loyal to a fault. So when someone double-crosses her, we wouldn’t be surprised if she focuses all her energy on getting revenge. We know how determined and intelligent Spencer is academically. Imagine if all that meticulous planning and drive went into exacting revenge on Toby once she finds out the truth? We’d be scared if we were him. 

Her entire future. Spencer barely got her application into U.Penn before the early decision deadline because she was so distracted by “A.” If that’s what happens when Spencer’s under a pretty normal amount of “A” pressure, what happens when she finds out that “A” is her first love? Not only would she risk screwing up her grades senior year, but she might wind up irrevocably risking her entire academic future. 

Not good, right? We hope there’s some positive outcome that we’re missing to get Spencer through. Share your thoughts in the comments!
