Harry nodded. "That is good." He smiled at her. "Different herbs need different amounts, and it is hard, but it can be done if you pay attention and really see what they react to best."

He gently patted the grass as he knelt next to her, his hands folding in something like a prayer formation unconsciously.

"Back home? Regular light, with applied use of will, by thinking of light, and of the flow of it, and of how it feels as it touches my skin. Sunlight? That is harder."

Harry swallowed as he closed his eyes and smiled. "Sunlight needs happy thoughts. Thinking of something that makes you smile, and gives you joy, real joy, in your life." Harry thought of Justine, and her warmth, her trust, the way she helped him, and the way she made him feel. And he stretched out his hand, thinking of the teachings the cove had given him, and how it felt to get something right. How magic felt, even here, and he blew out a breath as he grinned softly.

Soft and dim sunlight flowed over his outstretched hand, flickering there, and then gone, and then back in again, warm, and gently happy, it stretched out for the ground, and for Justine, seeking her like a blob with a mind of its own. It kept vanishing, or growing dim, but then coming back strongish.
