A/N: You'll notice that this chapter is a lot different from the first few. For one, it's shorter; the chapter didn't feel good long, so I left it up to my gut. Didyme is suffering from depression, for so long it had been her and Bella; the adults in their life expected a lot of them so naturally they clung to each other. Here it's Didyme's thoughts and ramblings as she's struggling to adjust to the idea of the supernatural, and the expectation of Bella to join the Cullens. There's also no dialogue or really any interaction with other characters, this is just a little peak at how the supernatural world is affecting the main character. You'll also notice that we're approaching the point where Edward leaves Bella, that won't change but be prepared for Didyme to change a bit in reaction to it. Anyways, as always anything recognizable is Stephanie Meyer's and all else is mine.

The rest of the summer passed by with ease, nothing of consequence really happening after the revelation in early June. I spent more time with the Cullens after the discussion on their dietary choices, and I actually found myself enjoying their company. Emmett was the funny older brother figure, while Alice seemed to like my sister and I equally. Rosalie was still the same cold and distant figure she had made herself out to be, while Jasper was slightly warmer but cautious. Carlisle and Esme took to the role of parents quite well, despite how physically young they both seemed to be.

The end of summer brought with it the beginning of the new school year, the start of my senior year. I'd never been entirely enthusiastic about school, mostly in part due to the people I had to go to school with rather than actually having to learn. Wasting my days away surrounded by Mike Newton, Lauren Mallory, Jessica Stanley and all the other gossipers of Forks felt worse than usual. Mike had not given up on pursuing Bella, no matter how happy her and Edward were, his puppy love was honestly sickening.

Before long, September had come and now it was the time of year when the leaves faded and rained down upon the earth. The world around was offset with fantastic ombres of orange and red, though there was still a plethora of green at every turn. Bella and would be 18 in just under two weeks; a large part of me ached over the idea that soon it would be time to set aside any and all childish delights. Growing up with mom was never carefree, she was so hairbrained that Bella and I had learned to split the adult responsibilities at a young age. Every other month we would switch off on paying bills, writing checks, whatever responsibilities Renee had forgotten or neglected. We'd spend our days cooking together–mom was and is a horrible cook, she often was overtaken by bouts of creativity in the kitchen, which was never a good thing.

Fall had always been my favorite season, watching the world change around me had been thrilling growing up, knowing that I was also growing and changing along with it. I felt slightly bitter lately though, while I wasn't changing all too much this year, my sister was. She had managed to find love and stability through Edward, she found structure; a place with someone who didn't force her to be the responsible one. I found myself alone. Every fall before now would have found Bella and I tucked into piles of blankets, making hot chocolate together and sitting in the quiet, reading side by side. We'd relish in the delight of Halloween, fused together almost–watching horror movies in the dark; we felt far too old to be trick-or-treating. I knew that would not happen this year, she'd replace me with Edward in the making of new memories. I would be left behind, allowed to tag along but still an add-on. It was Bella Swan and Edward Cullen now, Didyme was left to figure things out for herself.

I know my sister would not actively move to replace me, she had fallen in love with her boyfriend and naturally wanted to spend every moment possible with him. Anyone could tell he adored her; they reflected each other in a way that was both moving and simple. I couldn't find it in myself to dislike Edward anymore, even as bitter as I was that he held Bella's focus now. I tried not to insert myself too much into their days, though I was often extended an invite to the Cullens' with Bella, and the three of us occasionally spent our lunches at school with one another.

There was no way for me to stop from feeling as much grief as I had recently, it felt consuming–almost like I was sinking. So dramatic, it's not as though I had been completely forgotten, Bella still made an effort to speak to me, and occasionally we had sister bonding days. It just felt like there was a divide between us, Bella planned to join the Cullens in immortality one day, Alice had even seen her as one of them. She had even spoken to me about my own turning, but I did not feel the way she did; it didn't feel right to me, it wasn't my future. If one day I was made into a vampire, I would have to spend the rest of time as an afterthought. I would spend hundreds of years as an interloper, an extra party in Bella and Edward's epic love story.

I was just ready for winter, the beautiful changes in the world around felt like they were dulling quickly. As the days counted down, I just wanted my birthday to pass by with little consequence. There would be no tiny homemade cakes split between two sisters, no gag gifts or a birthday marathon of classic Jane Austen movies. I knew Alice was thinking of throwing Bella and I a party, I only hoped it would end early so that I could return home and spend the last few hours of such a special day alone.
