Ella had taken a ridiculous amount of injuries from the group of vampires that had turned on her while in her serval form. Back in her human form, she had deep punctures all over her body from the vampires, flesh ripped away beneath her loose clothing, bones broken. To say that no human could have survived that kind of attack was mostly correct except that Ella was not a normal human. She had a horcrux and that kept her soul alive even as her body died and began to process the venom pumping quickly through her bloodstream. Well, until her heart had stopped pumping and the venom had moved on to its next stage within her body.
Mostly unnoticed as they were covered by torn bit of fabric, Ella's wounds had very slowly started to heal. With her soul unattached to her body, her transformation from human to vampire had begun to progress slowly but surely, right on track...
There was order to everything. Transforming into a vampire or a werewolf, well, those had specific processes. Reattaching someone's soul to their body with a horcrux, that had its own process, too. What did not have a process, however, was someone being turned into a vampire while having a horcrux that was used to reattach one's soul only part of the way through the transformation. The results would be unprecedented, unpredictable.
Every possibility existed that this wouldn't work, that the two together would cancel one another out and leave Ella dead, forever gone. But as Terrence leaned over her, a very, very faint pulse began, a slow pulse. It was far slower than a normal human's heart rate should be. Another few moments and the blood trickling from Terrence's wound dripped onto Ella's skin, just above her chin. Without moving, without opening her eyes, Ella's tongue flicked out and touched the blood on her face and then, without warning, she was awake.
Not only was she awake, but in the blink of an eye, or less, she had moved from the couch and pinned Terrence against one of the poles holding up the tent, her hand firmly around his neck. Luckily, the bearings had strong enough magic holding them up that the tent did not collapse around them at the strength of the impact. Ella was fully conscious of her surroundings, even if completely oblivious to herself. Seeing Terrence, though, her lips curled upward in a mischievous smile, revealing two elongated, pointed, sharp fangs. Her eyes went to his wound and, without a word, she tilted her head up to run her tongue languidly yet hungrily just beneath his chin. Perhaps that would have made her realize something was different about her, but it was not like she had no precedence for enjoying the taste of his blood in her mouth.
