Talk:The Silence of E. Lamb/@comment-25160183-20140723192815

After watching this episode I'm 99.9% sure Bethany wasn't mentally ill. I think Mrs. D said she was mentally unstable and made up some lie to get her in Radley, because Bethany knew to much. Mrs. D joined the board to make sure she wouldn't spill. Bethany escaped the night Ali was "killed" and went to see Mrs. D. Mrs. D was so panicked on the phone, and she knew what Bethany was capable of, so she told Ali to stay in. Mrs. D started going inside after burying Alison, and Bethany was waiting for her on the back deck; Mrs. D was obviously upset. Bethany said she was going to get back at Mrs. D for putting her in Radley. Mrs. D, of course fragile and upset walked down the stairs, grabbed the shovel and hit Bethany. She thought Bethany was dead so she walked over to where Ali was buried and she realized Ali was pulled out, she dug and realized Ali was gone. She had Melissa run to the store and pick up the yellow top, and get an Ali bracelet. (Melissa obviously knows more than she's letting on) They put Bethany where Ali was buried (it would have been already half dug, because of Ali being pulled out) and put Bethany in the grave. There's going to be flashbacks in an upcoming episode, and Mrs. Dilaurentis is going to be in them. (A twitter picture confirmed she was going to be in upcoming episodes, there was a chair that said 'Jessica Dilaurentis') Notice how she didn't shed a single tear at Ali's funeral, was buying clothes for Ali, didn't go to the memorial, moved back to the house where Ali was 'killed' and buried, and wasn't at the house when the body was found, but knew the body was Alison's? "The yellow blouse is all I needed to see." but they weren't living in Rosewood at the time.

It's just a theory - but it makes a lot of sense.
