Talk:The Mirror Has Three Faces/@comment-82.73.190.52-20131017053821

I was watching this episode again and I noticed something. I'm not sure what it would mean, but the title is The Mirror Has Three Faces and we saw three of the liars in the reflection of a mirror; Hanna, Spencer and Emily. Could this be something important? A hint or a clue perhaps. Why was Aria left out?
