The preview of Pretty Little Liars Season 4, Episode 8: "The Guilty Girl's Handbook" from Canada's MuchMusic gives us new info about what's going down tonight (July 30). What can we learn from this promo that we couldn't figure out from the American one? We've taken a close look to see what new clues it holds.

Mona at the police station. What's Mona doing at the police station at :12? Is she turning on the girls, or helping them? The synopsis for this episode says Mona proves her loyalty to Hanna in an unexpected way, and the synopsis for Episode 9 hints that she commits a "selfless act." Could this be related? Does she claim she killed Wilden, or that she knows something about his death that would exonerate Ashley?

Eddie Lamb! At :17 we see a shot of Eddie Lamb, right after a voiceover about Wilden's death. Is this a hint that Eddie becomes a suspect in the Liars' minds?

A new guy? At :17 we also see a brief shot of a cute guy we don't recognize. Another new connection?

Pam sobbing. Why is Pam in tears at :18? She looks like she's totally breaking down. Is that because of the crash at the end of last week's episode?

"A" gets their screw on. At :18 and :19, and then again at the end of the promo, we see "A" with an electric screwdriver. Now that's a scary image!

More Mike. We see Mike brush Aria off at :19.

Hanna's plan. "I'm going to confess to killing Detective Wilden, and you're going to help me," we see Hanna tell Mona. Well, that's one way to help your mom, Han`...
