"What is wrong with you?" Lupin demands as he strides into the Gryffindor common room. Black perks up in the armchair he sits in.
"Nothing! Never better!" he says, grinning. Lily, sitting on the floor behind him, reading, tries to keep herself from laughing.
"What's funny?" Marlene whispers, finally looking up from her Arithmancy textbook; Mary already left for their dormitory.
"Oh, nothing," she replies. When she was younger, she used mess with her sister, Petunia, by mumbling nonsense such as jiggery pokery, hocus pocus, and squiggly wiggly and claimed they were spells. Sadly, Petunia got smarter over time, so Lily has not had this much fun in a while.
"What is wrong with you?" Potter demands as he prances into the Gryffindor common room. Black widens his eyes and cups his hands over his mouth.
"He won't say," Lupin explains, rolling his eyes. Potter glares at both of them with angered concern.
"Maybe he's pregnant," Marlene shouts. They look down at her.
"Don't you have better things to do?" Potter asks. Marlene ushers to her Arithmancy textbook and Potter turns away in annoyance.
"Remus, how much do you think Sirius weighs?" he asks. Lupin blinks in confusion.
"I'm right here!" Black protests, but Lupin seems thoughtful.
"Why might you ask?" he inquires, trying to get a good measure of Black.
"Oh, well, I was wondering how much easier it would be win in this Muggle fight."
"Right! That's still a thing!" Black says, squirming. Potter has enough and leaves for his dormitory.
"Sirius, I'm getting worried about you. Please, what's the matter?" Lupin asks. Black takes a deep breath then scampers to his dormitory. Potter then comes back down to the common room. "Going to the kitchens. Do you want anything?"
