Pretty Little Liars Season 4, Episode 18 Canadian Promo: Spencer Flipping Out (VIDEO)

Pretty Little Liars kicked things into high gear in the last few episodes, and we can't wait to see what happens now that Spencer has an inkling Ezra is evil. The recently released promo from Canada's M3 has us more excited than ever for Season 4, Episode 18 (“Hot for Teacher”).

The promo, which you can watch below, shows us more of Spencer than the American promo did, and it's clear that her newfound pill habit is driving her to the edge she even snaps at Hanna!

Another exciting moment from this promo that wasn't in the American version? At :05 we see Ali on the phone, telling someone, "Yes, that is exactly what you say." Who is she talking to? Shana? One of the Liars? We can't wait to learn more!

Also of note is Ezra telling Aria, "You have to start thinking of me as the person you are closest to." Ug. So creepy.

Want to know more? Here's the official synopsis of the episode:

With Spencer’s possible Board Shorts revelation, she is now more determined than ever to prove her theory before bringing it to the other girls’ attention – especially since it could have a devastating effect on one of the Liars. But with many sleepless nights fueled by prescription medication, Hanna starts to notice Spencer’s odd behavior. Will Detective Hanna be able to figure out Spencer’s secret before Spencer is ready to share?

Meanwhile, Emily looks to make amends with Alison through Shana, and all of Aria’s lies start to take a toll on her.

Check out the promo here!
