[Have a dubious look; he still has a hard time entirely accepting that someone so perfectly positioned hadn't spotted the culprit.]

[There are other names getting listed, too, because he and Supergirl were going to try and interview people during that party, but LOL handwaving. At any rate, that is most definitely the name of the Vongola's dumb cow brat mixed in with other names he likely wouldn't recognize.]
