Caleb is A theory's

For a while people have been talking about Caleb being A. I didn't really think about him being a but then I re-watched a pll episode and I think people may be right. here is why. there were 2 episodes where Caleb wrote a notes. there was one where Caleb tricked  Hannah  to meet him so he " pretended" to be A and there was another episode when Mona was back was back form Radley and  he "pretended" to be A. here are the videos.
