Like the sleep spell, which she'd already given him and took little more than a little rose oil, her fingertips, and some whispered words, Gretel felt the magic 'flow' through her- like an involuntary flex of concentration, a daydream that split her consciousness in two different halves. The focus in her eyes reflected the change as she muttered the words, locked on something Sam couldn't see, and didn't change or shift at his touch on her arm.
The press of his lips on her throat was a slightly different story. A hint of something warmer seeped into her gaze, a touch of deeper red in her lips and under the band of freckles across her cheeks and nose.
The glow faded shortly afterward, and the usual sharpness returned to her eyes. Over her shoulder, she smiled at him as she brought her wrists together over the bowl- the leather bracelets she'd made in place of her gloves and gauntlets the scientists had taken away when she arrived- with a fast strike of the flint and steel bits she'd woven into the design, a spark dropped into the ingredients, igniting everything with a bright blue flame that gave off no heat.
"Bring me the holy water?" she asked, her voice a little warmer than usual.
