Season 3 final epsiode

The Last epsiode of Pretty little liars season 3 was scary twisted and sad. I was so dissopinted in the end I wanted to cry. We found out alot on that last epsiode, like what the intials LJ stood for on the knife found in mayas bag, who A is and what mona did after she escaped from Radley. I can't wait untill the hawoleen epsiode with adam lambert comes out.
