He made a few sounds of muttered 'yes'es' his grinning growing wider as he just watched her. She was nearly beaming, and that alone was enough to make him glad of what was going on, that they were going home. She looked so spectacularly happy... He wasn't sure he'd be able to tell her 'no', even if the Healer advised them not too.
When she apologized Montague laughed and kissed her forehead. "Now if only I could get you so interested in Quidditch." He was teasing, he knew, while not nearly so avid a fan as he, still knew her fair share; it was merely the lack of playability that let them enjoy the game.
A small part of him, as he leaned down towards her, his lips moving closer, was waiting for the mood swing the other way, the one that meant she'd be disgusted by his presence and whining she was fat again... However, he was trying to be an optimist and leaned to kiss her lips, a short kiss before moving them to her neck. "And what might those be?" He asked with a grin, pressing another kiss to the soft skin of her throat.
