"My point," Peter said with a grin as he tapped one of the cards that Sirius put
down.
Sirius huffed and threw James a dirty look for distracting him from the game.
Irritable over the loss of one point, he purposely threw down a manticore card, knowing it
was already set to go explode.
"My poi—ouch!"
Snickering, Sirius shuffled the cards left in his hand. "My point."
"Mia said it's something called chronic migraines," James went on, gesturing to
Peter's hand and silently giving him tips on the game. "Says Muggles get them a lot. Makes
them sensitive to light or something. Probably why he stays in the infirmary when he gets
them."
"We can get Muggle diseases?!" Peter exclaimed loudly and dropped all of his cards,
a look of horror and disgust on his face. Two of the cards exploded in a puff.
"Of course we can, Pete." James rolled his eyes, waving away the smoke. "You've
had the flu before, yeah?"
"Yeah. That's a Muggle illness?"
"Some of theirs we can't catch, and some of ours they can't get. Muggles can't catch
dragon pox," Sirius explained as he gathered up what cards were unsinged, a bit put off by
the tone in Peter's voice.
"Lucky them."
Sirius laughed at his friend. "Yeah, their pox is called chicken."
"What do they do with chickens to get sick from them?" Peter asked, looking
disgusted.
"What do we do with dragons?" Sirius countered with a wry grin.
"Can you two shut up for a second?" James groaned, looking stressed out. "What's
our Potion lesson this week?"
"Sleeping Draught," Peter said. "Remember? Frank messed his up the first time and
had to be sent to the hospital wing for a Wide-Eye Potion."
"Does the Sleeping Draught contain aconite?" James asked quickly.
"Aconite? You mean monkshood?" Sirius looked up at his best friend with raised
brows.
