Before tu go all hater on me, just hear me out! I don't hate Ezra o anything but it makes sense if tu think about it.
1. A didn't come up until Ezra turned up. Why would he go to Ali's funeral, anyway?
2. Marlene King dicho that, in the first season finale, one of the girls would have a fight with Ali's killer. So if Ian isn't the killer, what about Aria's fight with Ezra about Jackie?
3. In the first mid-season finale, Hanna was run over por a car because, according to A, "she knew too much." So if A wasn't Noel, it could be Ezra because Hanna saw him and Aria together.
So there tu have it. What do tu think?
Sorry this is really short.
