It was Lydia and she knew it, she knew that Sarah would never do such a selfless act such as killing herself, she knew that Sarah would never leave her father to cope with her death and to look after the kids until Amy came back, she knew that she would never leave all of her friends so suddenly, she knew that she wouldn't leave her on her own and eventually lead her in to this hellhole of a place and she knew that Sarah would not leave Lydia to grieve over the death.

Zoe didn't deserve to be in prison and she knew that she didn't. She spent most of her days in her cell thinking of Sarah, remembering all of their memories together, and even their falling outs.
She could remember that night when something happened between the two of them, she could remember the way that Sarah felt on her skin, and how her kiss tasted, and although Zoe never felt anything but friendship for Sarah, she would do anything to feel that now, she wouldn't mind at all because it would just mean that she would have her best friend alive and breathing and she wouldn't be stuck inside of this cell for doing something that she hadn't even done.

Zoe was puzzled at how Lydia could actually kill Sarah when she was supposedly so in love with her, how could she do it? How could she actually bring herself to do whatever she did and why? That is what puzzled Zoe the most, nothing made sense to her about this at all. How could Lydia actually watch was happening when they were all falling through the same sky, how could she look at Sarah and watch her fall to her death?

Unless it was never meant to happen, what if it was never for Sarah? What if the accident was actually intended for Lydia to try and kill herself, it wouldn't surprise Zoe as she knew how mental Lydia really was. She knew that there was something wrong with her head as soon as she started to tell all the lies about Sarah that she did.

Then it clicked in Zoe's head that Lydia was telling these lies because she was jealous of how close Zoe and Sarah were and it was at that moment that Zoe realised that the accident was intended for her. Whatever Lydia did to mess things up, it was supposed to be Zoe who the body belonged to in the wheat fields but still, what would be the point in doing that?

It made sense that Lydia would kill Zoe or attempt to or even just set out to just because her and Sarah were closer than Lydia was, but then again, why would Lydia take away the one thing that made Sarah truly happy? Surely, it would just drive Sarah away from her.

It was a messed up world, it was so very messed up, that Zoe couldn't even go the funeral of her best friend, yet a psychopath of a true murderer could go and people would feel sorry for her, until they found out exactly what she was.
