The celebration banquet was held at the Duke's mansion.
Anning, as a country bumpkin who couldn't dance, basically just hung around the edge of the dance floor snacking. The refreshments provided by the Duke's mansion were quite delicious, allowing Anning to feast to his heart's content.
It seemed that Robespierre wasn't too keen on dancing either, so he came over to Anning and started a chat.
Anning first took a jab at Robespierre's coat: "Why are you still wearing this green coat? You should have worn something more formal for tonight's dance. Even I borrowed a suit from the Duke."
Anning had previously bought formal attire, which he wore out to a duel today, but got shot in the shoulder and stained it with a large bloodstain, rendering it unwearable.
Since that was Anning's only formal attire, he had no choice but to ask the Duke for a loan.
