I've been watching Pretty Little Liars and I cheated and did a search on who's A. The answer seems to be it's ...I'll try not to spoil it.
There was a list of reasons why the person that was revealed was A which on the outside makes sense except at the same time I was watching an episode (I'm on S2E10) it had a scene where Emily was getting a massage and finds out A was in the room (the glass has an A in the condensation), it then cuts to the named person sitting in a car (Aha!)except the person is with Spencer at the school and seen by Aria's mother, it then cuts back to Emily walking out of the massage room and gets a text message from A. So either A is magical and can be in 2 places at once and able to send texts with their mind or they can't be A.
Do you believe the person named is really A?
