“I asked you to help me with Potions, not to sit on my back and play Pokemon,” Bruce said.
Tony might have noticed that he sounded more irritated than usual, but his Flaafy was so close to evolving.
“Tony!” Bruce said, louder this time, but it almost immediately turned into an exasperated sigh. “I regret giving that DS to you. Where did you get it charged anyway? I thought you ran out of battery a few weeks ago.”
“Oh, I meant to ask you,” Tony said, not looking up from his game. “Why don’t we have a generator power thingy set up in our room? Jane has one set up in hers to charge all her Muggle stuff. Electricity is basically what Muggles have instead of magic, seems like.”
“That’s–wait, Pepper let you into the girls’ dorms?”
“Pepper was busy putting out a fire in the common room.”
“A literal one?”
“It might have been breathing literal fire.”
“Only a little!”
Bruce sighed again and looked back at his cauldron, which was bubbling a little faster now as the potion heated up. “So are you going to help me with this homework or not?”
“You put too many cricket legs in,” Tony said, still not looking up from his game. “It should explode in another few seconds and then you can start over.”
“What?” Bruce looked down at his notes, then at the textbook, then quickly at the cauldron again. “Why didn’t you–”
And then the potion exploded. After that, Bruce didn’t ask for Tony’s help anymore.
