Could possibly.(Pretty Little Liars theory)

We know Ezra is A. But we dunno why. Here is my theory. Maybe he want to protect Aria from big A. We saw basement in the cabin inn the woods.(lol) Anyway maybe he thinks like that. "If I could hide Aria from him/her." Hope so like it or I never forgive him. My bad theory is Ezra bad at all. But why? Hope we can learn him quickly. And something in my mind. Hannah says" Alison maybe she is in troble livin' in rail or something like that. So look at this picture what you see.
