The Pretty Little Liars promos from Canada's MuchMusic are often really good, but the one for Season 3, Episode 4: “Birds of a Feather” (airing June 26) absolutely knocks our socks off.

"The girls discover that even the truth can lie," says an ominous voice over. Based on this preview, it looks like the girls uncover some uncomfortable secrets about Melissa (Torrey DeVitto) — we even hear Hanna (Ashley Benson) say "Melissa's 'A'"!

We're not sure if that will turn out to be right, but it looks like the Liars find some feathers in a closet (Melissa's?), which makes us even more suspicious that Melissa is the Black Swan.

Also of note: Someone is offering a $50,000 reward for info on where to find Alison's (Sasha Pieterse) remains. Sounds like that might be why Jason (Drew Van Acker) is writing a giant check...
