It’s not surprising that the cast of Freeform’s Pretty Little Liars loves Hocus Pocus. After all, what’s not to love about Bette Midler, Sarah Jessica Parker, and Kathy Najimy playing three witch sisters who do things like make a room full of people dance until they die and turn teenage boys into talking cats?

However, there’s one Liar whose connection goes a bit deeper than just a love for the film. Troian Bellisario, who plays Spencer on PLL, has a particularly unique story: She went from having a crush on said boy-turned-cat, Thackery Binx, to calling him her step-brother in real life after their parents fell in love and got married. (Does that mean Mary Drake is his mom, too?)

Watch the Pretty Little Liars cast share all their Hocus Pocus stories in an exclusive video above.

Pretty Little Liars returns to Freeform in 2017.
