Why Cece was at Alison's "death"

Not many people has been thinking about this question, but why was Cece at Alison's "death" so I have decided to do a theory on it.

Why did Jason see Cece at Alison's "death"?

We know that Jason was wasted so his sight and memory are probably blurred and possibly incorrect but I don't think that the PLL writers would have included that bit if they didn't want us to think about it.

Theory #1 - The Pranksters

My first thought was that Cece and Alison were playing another prank on Mrs DiLaurentis. The girls were always playing pranks according to Mrs DiLaurentis and is Mrs D didn't let Alison get her way than who knows what the girls could have been up to...

Theory #2 - Cece is the "Beach Hottie"

This is a far fetched theory but mainly the only information we have about the beach hottie was from Cece and we now know that she is part of the A team! Either she was completely lying about the whole thing to protect herself or she was really doing the girls a favor and telling them the truth. Or she was possibly protecting Ezra by leading the girls to think it was Wilden. Pick your theory.

Theory #3 - Cece is the "muderer"

So Cece stalks Alison all night long and leads her to where she wants to bury her. She gets some help from Ezra to hit her on the head and then dig a hole big enough to bury her. They don't know that Alison can survive long times without breathing so they are out to get her.

Theory #5 - Alison, the boyfriend stealer

Another theory is that Cece was dating Ezra and Alison came along to claim him as her boyfriends. The girls used to share everything together, even eachothers lives so why not share eachothers boyfriends. So Cece got angry at Alison and killed her.

Theory #6 - Cece and Ezra have it all planned out.

Similar to Theory #5 but instead Ezra pretended to be Alison's boyfriend but really was dating Cece. Cece was in on the whole thing and she went along with it. They did it so Alison would trust both of them and they still met up in secret. Cece secretly hated Alison for some reason - possibly that she got her kicked out of college or maybe something even bigger.
