Looking back for a moment when she smelled smoke, she seemed like she might argue with him before she stopped herself, instead going back to her vials. After picking out a few that she wanted, she set them aside, for the time being enjoying watching the body slowly slipping out of existence. Once it was gone, she finally returned her attention to the demon, leaning back against the desk with her hands resting on the edge.
"The second part was what he didn't enjoy." She admitted with a dark smile. The witch seemed to almost laugh to herself, before the humor disappeared, and she shrugged her shoulders.
"I'd had my fun playing with him, I told him I'd drain him dry-- he just didn't know what exactly that entailed. Who knew humans would be so upset about having their blood taken from them? He struggled so much. A valiant effort to say the least, but in the end, all for not. I wanted his blood, I got it." She shook her head, almost seeming to smile fondly at where the corpse had been. Breathing deeply, she then out with a short sigh, soon turning back to her work.
"But to answer your question, his blood was going to be used for a spell. Nasty little boy lied to me, so the spell didn't go over as well as I wanted." She explained, gesturing to all the blood that was now all over her pretty things.
"I can still use it for something else, I guess, but he made such a mess. And no matter what I do, it never fully comes out of fabric. Your fabrics just look ... off afterwards. Not stained... just ... off." Again, she twisted her face into a look of disdain, before finally turning back towards the room. Raising her hands up, her robes fell away from her wrists and down to her upper arms. She began to recite an incantation of some sort, something in one of the older tongues. Soon the blood became a mist, reverting from its coagulated--and in some places dried-- form, soon collecting in an orb above the bed. It slid its way towards the witch, who directed it to an empty, open bottle by her side. Once all was in it, she picked it up and corked it, setting the blood bottle aside for the time being. The room was now cleaned of the blood, no evidence of any corpse to be seen. Even the smudge on her forehead had disappeared. Cassytha sighed contentedly then, setting her hands on her hips and smiling towards her companion.
"Much better, don't you think?"
