"Wait! Sirius, come back!"
"Come now, Regulus," his mother smiles. "I want to hear all about your term."
"You can't just let him leave like that!"
"Don't worry about him." Regulus's father pats him on the back. "How's school, eh?"
Impulsively, Regulus reaches for his wand, despite not knowing what he can do with it. But his mother reaches for his hand. "Mum, I'm not a child, I don't need you to hold my hand at the train station."
"Well, tell us how life is, we haven't seen you for months!"
"And when's the next time you're going to see Sirius, huh?"
"That doesn't matter right now."
"Can I go run away? Are you going to stop me?"
"What would you want to run away for?" his dad asks.
"Dunno, why don't you go ask Sirius?"
"You're not Sirius," says his mother. "Come on."
