The Canadian preview for Pretty Little Liars Season 3, Episode 7: “Crazy," (airing July 24) is just as fun and creepy as we've come to expect of the promos from our neighbors up north.

In it, we see Detective Wilden (Bryce Johnson) tell Hanna (Ashley Benson) she needs to come into the station for a blood sample, and then the voiceover teases "to save their best friend, the girls have to face their worst enemy."

Check out the preview below!
