Nero watches eagerly to see what he'll do. Look, this is such a low-stakes thing to challenge him on. Possibly the first low-stakes thing they have ever, ever had to discuss between them. It makes no difference to him if Vergil puts this or that on his fries, but watching him debate over it is absolutely priceless.

He chuckles, not remotely affronted by the reaction. "If I've got all the ingredients, sure. At a restaurant where they got all this on hand is the perfect place to make it. And honestly? If you put mayo, mustard, and ketchup on your burger, you're already eating it anyway."

With a muted smile at Vergil, he picks up his burger and somehow does not have to unhinge his jaw to take a few bites. It does involve a lot of work with angles.

Man. Here he is. Going out for burgers with his father.
