'Pretty Little Liars': Emily's on a stretcher, is Shana to blame?

pretty-little-liars-turn-of-the-shoe-emily-hurt.jpgABC Family has released some pics from the second episode of "Pretty Little Liars" Season 4, called "Turn of the Shoe." We already know from the episode description that there are some "potentially devastating circumstances" for Emily, which is certainly supported by the above photo of her on a stretcher in a neck brace.

Below we can see that Shana ( Aeriel Miranda) is back and in the locker room, seemingly prior to Emily's injury -- is she involved? She certainly doesn't seem very trustworthy.

And also below, the other Liars are looking concerned about something on Spencer's phone in her house at night. We can't wait to find out what it is.

Unfortunately, there are no photos of Mona's fate -- but we do know "A" nearly kills her in this episode. Yikes.

"Pretty Little Liars" returns Tuesday, June 11 at 8 p.m. ET/PT on ABC Family.
