Ace snorted back a slight laugh, wondering if she should leave the pair of them alone. "Well, I'm sure it would give them a bit of a headache if they had to figure out how many people saw Ari's wand under the ... table."
She exhaled a faint sigh, then decided she'd spent too much time listening to the kids if she was thinking about wand jokes. Good lord. She did sneak a glance toward Ari and Neville, but she had a feeling she couldn't stay here and not giggle.
"I should ... probably go see if anyone else has managed to walk into a bludger today ..."
Ari tried not to grin, though Ace's repressed giggle wasn't helping. "Well, if you wanted to," she said to Neville. "I certainly wouldn't mind."
That comment eked another laughter-sound from Ace, and Ari glanced over toward her with a grin.
