Beauty And The Beast

Changing

"I don't know how to explain it," Carlisle said, listening to Rosalie's heart, which was actually beating. Not like a normal human's though, it was like one beat every few minutes.

Stiles stood beside her, leaning against the table for support, still really weak from spending the whole night healing.

"It's like some of your mortal bodily functions are returning," Carlisle said,"You have tears, your heart is beating even though you don't have blood flow."

The pack had reluctantly let Rosalie stay with Stiles the whole night, and as soon as they could they came back to the Cullens house.

"Do either of you know what could have triggered it?" Carlisle asked.

Rosalie and Stiles looked at each other, both of them racking their brains for an answer.

"My blood," Stiles said,"She drank a bit of my blood, but not really drinking, it was more like a drop or two."

Carlisle looked between them in surprise,"Don't look at us like that," Stiles said,"It was an accident."

"May I take a sample?" Carlisle asked.

"Uhh... Sure," Stiles said, holding out his arm and Carlisle pulled out a syringe from his home doctor kit.

The doctor pressed the syringe against Stiles' skin, and his brows furrowed in confusion as the needle refused to penetrate the skin. Carlisle pressed harder, and the needle snapped against Stiles' skin.

"Huh," Stiles said both surprised and worried,"That's never happened before."

Carlisle took Stiles' arm and started pressing against it in several places.

"Your skin... It's similar to ours now," Carlisle said, looking at Stiles with a new interest,"You still have blood flow, but your bone strength is... well, indestructible. Your body is adapting to the trauma that you experienced so the next time that something like this happens again it will be able to withstand the force."

"English, Doc," Stiles said frustratedly.

Carlisle let out a breath, smiling at Stiles as he realized what a marvel he was,"What kills you... Only makes you stronger."

Rosalie looked at Stiles with wide eyes, she didn't think he was breathing, she had to nudge him and he gasped for breath.

"S-So..." Stiles stuttered.

"You're a survivor in more ways than one," Carlisle told him,"Theoretically, if you were to drown you might grow gills. If you fall from a plane, it's possible you could grow wings."

Stiles shook his head, as if he could stop everything that was happening with just a shake of his head.

"W-Wait, but what about Rosalie?" Stiles said, returning to the reason why they were there.

"Without a blood sample I can't be sure," Carlisle replied, looking at his adopted daughter,"I'm sorry."

Stiles looked down at his arm, then to the syringe, an idea forming in his head.

"You said my body adapts to defend against anything, right?" Stiles said.

"Theoretically," Carlisle replied.

"Well..." Stiles said, flicking out his claws, glad to see that that hadn't changed,"What if it can't defend against itself?"

Stiles brought a black claw to his arm and started digging it into a vein, and the claw sliced right through the skin and red blood started gathering around the cut immediately.
