Out of all the older vampires, Cooper has been most anxious for Jean-Claude to arrive at the party. The rest bothered him only a little. He would take note of and remember later on, but if the head of the Nest failed to show, tongues would wag about how it was a clear sign that he didn't approve of the new representative. Even if that wasn't true, other vampires would take note, and pick sides. Then they'd be working at cross purposes, exactly what Cooper didn't want to happen.

So he lit up like a candle flame when he saw the very flamboyant vampire approaching him. "Salutations monsieur," Cooper replies in heavily-accented, atrociously sounding French. He takes the box. a look of surprise quickly running over his features. "For me? Merci."

It might be better manners to wait until he's alone to open it up, but Cooper is curious as to what is inside. And if it has any magical properties, it's better to have Jean-Claude tell him what it is right now rather than discovering them for himself.
