Everyone wanted to know who the person under the hood is in "Pretty Little Liars" and when the cast found out who the person was, they had to ask if it was really true. The cast and crew has finished filming for the ending of the series last year so they already knew A.D., TV Guide reported. But no one wants to spoil the thrill; the cast just said that they were shocked after they found out.
