"You won't have to," Hermione tells him, and then pushes up on tiptoes again and brushes her lips against his cold cheek in a kiss, to seal the promise. "I'll hold you to it though." He smiles at that – a genuine lopsided grin – and agrees in a murmur as he tucks her arm through his, and they start off again. They move further into the winding green and white maze, heading toward the very centre and that peaceful little spot where he has woven her daisy chains, and pointed out constellations, and made her feel free.
