PLL Theories

Red Coat theory.

For this theory I give credit to @Bethany_is_a on IG!!

So, 3x01 we know someone dug up 'Alis' grave. Then we know that it was -A and Red Coat. So Red Coat makes -A do the dirty work.. But why dig up a grave? I have a few reasons.

1) to check if it was really Alison. She had everyone fooled that she's really dead. I don't think Red Coat or -A really knew the truth even if they see everything.
2) To switch the body. I have a theory about this but that will be a different post.
3) make the body look more like Bethany.
But why make it look like Bethany? I have a few theories about that too.
1) The Red Coat was actually Bethany. The person in the grave is Sara Harvey And Bethany knew Alison was alive. She knew that she's going to come back because Alison told her. They kept in touch and Bethany would work with the -A team to get info for Ali. So, after Alison came back they would have to look at the body again and guess who it was, so they had to choose Bethany Young as she looked exactly like her. Actually both Bethany and Alison are alive but because Alison made Bethany do things for her, Alison made the cops not look for Bethany and put her back in Radley.
2) The Red Coat is Alison and she wanted the body to look like Bethany because the body is Sara Harvey, she doesn't want the cops to know its Sara because Alison was the one that killed her. She not only made her life easier as the cops won't know that she killed Sara but also Bethany's because people won't look for her and put her back in Radley.
