St. John didn't actually have a drink all the time these days, except for how he totally did. But tonight was a party, and so he was allowed to drink some. That was totally expected.
What was not expected was Marie-Ange showing up with some guy. John didn't recognize the Guy, which wasn't a surprise, but he felt his teeth clench anyway.
He told himself to stop being an idiot, because he had no reason to be angry if Marie-Ange had a boyfriend, but he still really wished he could make things burst into flames just by looking at them.
