A joint Arithmancy and Muggle Studies lesson?

Now this would be interesting.

Simon walked into the classroom with the usual casual backpack laxidasically hanging off one shoulder and eyed the rather festive kitchen. Were... Were those sombreros? He eyed them carefully and then turned to greet the Professors. And he only saw Hadley. Huh?!? Where was Domingo? Busy hiding something? He didn't know what to make of her but decided to ignore that thought and smile at Hadley instead. "Hola Professor Hadley! How are you?" he said as he slipped a sombrero onto his head and made his way further into the kitchens. With his sombrero, the only thing he now needed was a nice mustache like the one Luigi had from Super Mario Bros. That would be perfect.

He spotted Sophie sitting next to Grayson. Ooh getting cozy, huh? "Hola señorita and señor," he said, smirking as he walked past them. Oh, ho, ho. Where was Domingo when you needed her to give them both a wink? The boy continued into the room, making his way over to Cutty, Ethan, and Zander. "Hola amigos!"
