Nevin was not ashamed to admit that when Eteri stopped moving in his arms, he may have panicked just a bit. He had to keep her alive while he figured out how to reverse the damage that the plant had done to her while it was in her system. But the problem was, he didn't have the kind of medical equipment that he would have liked to have to keep her breathing and her heart beating. All he had was -
This would hurt. But she was already hurt, suffering, and so painfully still. Nevin took a deep breath and from over his chest threads began to emerge, weaving into what would look to any observer like a large spike with a painful tip. Nevin's skin tone paled as this spike began to glow with a brilliant crimson hue, lighting up the interior of the building with an eldritch glow. He took a bother, shaky breath, and the thread spike slipped into Eteri's stomach. The glow faded from the room - and she began to move again, weakly.
It was working. Nevin watched, breathless, as her chest began to rose and fall again, and she stirred. He gritted his teeth and pushed. The thread between them glowed again, in a wave that rolled from the alchemist to the cat girl, and when it reached her it spread out, defusing across her skin and bringing more color back. If there was anyone who could see what he had done, they might have called him an idiot.
Bu he would do it again with no hesitation. Sacrificing some of his life force had restarted her bodily functions, enough to keep her going now that the worst of this was over. The spike of thread slipped out of Eteri, leaving a red mark on her stomach where it had merged with her skin. The rest of his threads were moving more sluggishly now, as they gathered medicines and antidotes. Now that it - now that she was not in immediate danger of death, her symptoms mimicked some poisons, enough that a general serum should help.
Getting her to drink it took effort - and in fact, drastic measures. Trying to hold her mouth open wouldn't work - the serum just trailed out of her mouth before she could swallow it. Grabbing another vial, Nevin took a deep breath - then poured the medicine into his own mouth. He leaned forward quickly and sealed his mouth to hers, keeping it in until - until she swallowed and began to stir more. He sat up in time to see her start to open her eyes. A gentle thumb wiped some of the spilled medicine away, and then he pulled her close to him.
He didn't know what she was saying, but the confusion in her eyes made it clear. After wiping his face and pulling away from her neck, he shook his head hard, red hair flying around his face before he stared into her eyes.
"N-no eating strange things, Eteri. Almost lost you there." He knew his voice was trembling, like he was, but he didn't really care. He didn't know what on earth she had been working on, but it was in no way near necessary for her to almost die for it. It couldn't be worth it.
