Courfeyrac had Anna's help setting up the table outside for their later plans, yes... But after having a quiet chat with Jehan, he managed to get the promise that he could treat his date to a nice meal before they helped out with the cafe.

He waited for her at the Big House, having swapped his jeans from earlier that day for a nicer pair of slacks, and even a sports jacket. He would have picked her up from her cabin, but....

He hadn't yet told Enjolras that he'd asked his sister to be his valentine... And Enjolras scared him sometimes. (Especially when he finds out what he did with that flower order earlier.)
