She pushes her hair out of her forehead.

"Wicked! Wanna grab a compartment with me?"

"Sure, why not."

The twins help them with their stuff and on they go to an empty compartment near the back of the train.

"What's that?" says the other twins suddenly, pointing at Dorea's lightning scar.

"Blimey,” says the first one. "Are you—?"

"She is, you can look later." He looks at Dorea. "I'm gonna say bye to Mum and be right back, alright?"

"'Course."

They run off and their mother is just outside Dorea's window. She can hear their exchange.

"Ron, you've got something on your nose," says their mother, grabbing the youngest boy and rubbing the tip of his nose with a handkerchief.

"Mom—geroff!" He wriggles free.

"Aaah, has ickle Ronnie got somefink on his nosie?"

"Shut up."

It must be nice to have a Mum.

It probably is. They exchange some banter when the oldest boy—Percy—arrives. He's apparently a Prefect, and has apparently not shut up about it all summer.

And their mother tells the twins to behave and not blow up any toilets this year.

To which they reply they've never actually blown up a toilet but that's a great idea.

And they also inform her that they met Dorea Potter and suddenly the little girl really really wants to board the train.

Aww. 

One of them wonders whether she remembers You-Know-Who and their mother becomes suddenly very stern and forbids them to ask. They promise to send their little sister loads of letters and a toilet seat and then a whistle causes them to hurriedly board the train and wave at their mum from a window until the train disappears into the tunnel.

"I don't remember, I was only a baby," she says once they're well out of Molly Weasley's earshot.

"Makes sense, I guess."

"But hey, listen, we're going down the middle of the train—Lee Jordan's got a giant tarantula down there."

"Did we introduce ourselves? Fred and George Weasley. He's Ron."

"I already told her my name."

"Oh, alright. Anyway, bye."
