Today, it's all about TV's newest of master of mysteries Spencer Hastings, played by Troian Bellisario. (Ya hear that? Step aside, Nancy Drew!)

Not only did we get the exclusive details on Spencer and Toby's "bizarre" relationship, we also snagged the inside scoop on how much longer PLL will be bringing us thrills and chills before "A" hangs up the hoodie for good. Spoiler alert: Troian says she definitely does not want to be a 35-year-old still stuck in high school. So the clock is ticking, people!

As for Spencer's multiple dabbles with the dark side? Bellisario hopes that Miss Hastings will continue to toe the line between overly assertive problem solver and answer-obsessed psycho. "I'd love to play a villain!" the 28-year-old star gushed while sitting in The Brew, the PLL version of Central Perk.

Do yourselves a favor and immediately click on the video above to watch our exclusive interview with Troian and find out what kind of havoc Ali will wreak now that she's back in town.
