I think Meredith is Jason's twin sister. She is mentally ill could have been sent to radley or something and I think she was the one who tried to kill Alisson and Mrs. Dilaurentis saw this and protected Meredith. Maybe if she was at radley she was the one who pushed Marion. She leaves in season 3 so I think she will play a big part in all of this.
