In the end, all the way up to her final breath, Jenny had been hated.
It wasn't like it was without reason. If asked why she was so despised, she would have cried and claimed that she didn't know why; she would do anything she could to make whoever would listen pity her so maybe, just maybe, they would forgive her for her sins against them. It was a bit degrading to carry on like she did at times, but it got her the attention that she wanted so badly. Even if the attention was negative, at least someone was giving it to her. At least someone was acknowledging her. At least someone was fucking paying attention to her. In the end, that was all she wanted. She wanted someone-anyone-to give her their devoted attention. Adele had worked for a while, and then Nikki, and then? Well, then she got who she truly wanted; she got Shane, the most unattainable person that she had ever met, to care about her. And for a while, that had been enough.
Her attention seeking ways had cost her almost all of her friends. She had become so hated that each remaining group member honestly had to wonder who it was that had murdered her. The truth had eventually came out about everything-they all knew how each felt about her. There was only one secret left to be found out.
Helena had been upset because Jenny had told Dylan about their plan. Alice had been angry because Jenny had stolen her story. Tiny had been furious when she had finally found out that Jenny had stolen the missing film. Shane had felt numb after realizing that Jenny had hidden Molly's letter. Bette felt anxious about Jenny ruining her family. Kit had felt overprotective of her baby sister's life. Jenny had been irritating Max lately.
They each had their own motive. The only secret that was left to be uncovered...
In the end, all the way up to her final breath, Jenny had been hated by everyone, but mostly by herself. In the end, she had taken her own life. In the end, she freed them from their burden.
