He was showing off now, and Constance laughed, the bright sound dimming with memories of her favorite show-offs. Porthos and Aramis were more likely to use their guns for it, but gambling on their skills had earned them coin more than once, not that they needed the excuse. And they would've been the first to challenge him to some kind of pistols versus knives just for the fun of it.

Athos was far more practical, and would've feigned disinterest in any such games (while watching intently from one side), but she could imagine him appreciating how finely crafted the dagger was.

Constance wasn't Aramis. Or Porthos. Or Athos. So her reaction was different too. She bit at her lip, considering, the same flash of enthusiasm in her eyes she'd once given for pistols and for swords. She leaned forward, drawing the dagger from its sheath at her back – slowly, because men that at ease with weapons could react to potential threats before they had a chance to think – and held it the way he'd held his. "Enseignez-moi?" she asked, pointing with her free hand to his dagger, and then at herself.
