He inwardly panicked for a moment, but didn't let it affect his expression. "Yes, well... isn't she in class currently?" He held his hand behind his back before flicking his hand. Lilith, around the corner, would start levitating.
Lilith looked confused and a little panicked, but said nothing. "No, she's home today. Otherwise she would have her halo with her."
"Oh, I see," he said, waving his finger as she was quickly brought up to the window. "Well, yes, you might want to let her know."
He nodded, turning and heading up the path. As he waved a hand, the window reappeared in Lilith's room.
He grinned, flying up to her and placing his hand against the window. The matter rippled before disappearing once more.
