Fionna's gray hair was just poking our of her bunny hat, like it had done those many years ago when it was still young and blonde. Her skin was tired, worn and covered in scars that echoed her years of being able to fight. She of course hadn't fought for about a decade- her human limbs were becoming old, slowly wasting away into nothing.
"Stay with me, Fionna," I pleaded. But it was no use- she was going to die any minute now, I knew it. Her blue eyes were barely even open, yet the whites of them were showing alarmingly. "Fionna..."
"Marshall Lee? Is that you?" Her voice was barely a whisper. A single tear escaped from my eye- this was the third time she'd asked that question in the last few minutes. I felt like every time she looked away from me I was fading away from her memory.
"Don't go. Please, Fionna." Then an idea flashed into my head. I was immortal- and if I bit Fionna there was a chance she could be too. But would she even survive it? Her body was weak- too weak. I suddenly remembered a conversation we'd had, sitting at the top of her treehouse. Cake had been out with Lord, Gumball had been doing another useless science experiment and nobody was in need of saving. No, it was just me and Fionna.
"When you turned into a vampire... What was it like?" she asked.
I shrugged, not really wanting to talk about it. "I can't really remember, it was so long ago."
"But you must remember. Getting turned into a vampire isn't something you'd forget in a hurry."
"Just shut up about it, Fi. I don't wanna talk about it." Fionna sighed, then took a deep breath.
"I just... Was wondering... Marshall, can you turn me into a vampire?"
"What?" I thought at first she was joking, but when I saw the earnest expression on her face I knew she was deadly serious. "Seriously, no. Being a vampire is not some little phase. Once you're bitten, that's it, you're stuck."
"But- I'm going to die. I'm a human, and.. I want to stay, with you." She was blushing now.
"No. I'm sorry- I can't." I put my arm around her but she shrugged it off, turning round to face me. Tears were glistening in her eyes, and she gave a sob before burying her head in my chest. This was the first and only time she had cried in front of me.
"Marshall? Is that you?" Fionna was now an old woman, but I could still here the voice of the fresh-faced young girl when she spoke. She tried to sit up, this time more urgent than the times before when she'd asked the same question. She forced herself up into a sitting position, but began to breath heavily like she had just ran a marathon.
"Marshall Lee..." She whispered, before her head fell back onto the pillow and her body froze still.
"No... No!" It was no use.
Fionna was dead.
