Niet's pretty used to the basic concept, so she nods and looks around for a clock.

It is Late o'Clock.

Yeah she would like it to be Sleep o'Clock. Bedrooms?

A spiral staircase off the common room leads to the girls' dorms.  (Another one leads to the boys' dorms but that's less relevant to her.)

She yawns and heads up. If beds aren't pre-claimed, she'll wait for everyone else to grab somewhere to sleep, but otherwise she falls straight into her bed.

Her dorm-mates appreciate this.  Zzz.

Harriet sleeps lightly and wakes up extremely early. She knows how to be quiet, though, in the early hours, and she very gently fetches a book from her trunk - after reminding herself she's allowed to do this now - and tip-toes down the stairs to read in the common room until breakfast time.

It's dark and quiet, for a while; but eventually one of the Gryffindor boys descends the stairs yawningly.  "Morning."

"Morning..."

He rubs his eyes and squints curiously at her.  "I saw you on the train, didn't I?  You were looking for a toad."

"For a little bit, yeah."

"I was in the compartment with Ron," he says.  "Ron Weasley, red-haired bloke.  I'm Dean Thomas.  Find your toad okay?"

"Oh. Yeah. Someone brought it to the prefects."

"That's good."  He gives her a bright, genuine smile and plops down in a seat next to the fire.

She eyes him, then pretends to return her her book. (She's too nervous to actually start reading again right away.)

Dean, oblivious, takes out a wizard-chess set and muses over it as the pieces arrange themselves into a puzzle ("white to mate in three," the white king informs him smugly).

Ron and another Gryffindor boy are down soon as well; Ron yawns and looks over Dean's shoulder and moves one of the knights.  Dean "Oi!"s and shoves him away playfully.  All three laugh.

Hermione's down a little while later.

She stops by Harriet's chair and peers at Ron and company.

"Are those the boys from the train?" she says, eyes narrowed.  "The ones who were rude about Trevor?"

...Awkward shrug.

Hermione watches them for a few moments, with narrowed eyes, then marches over.

Ron looks up at her a bit blankly.  "Hello."

"You were rude about Neville's toad," she says firmly.  "I think you should apologize."

...She really hopes they don't get into a fight. That would be terrible. (Even if Ron should apologize.)

" - when?"

"On the train, when we were looking for him.  You said, if I had a toad I'd lose him as quickly as I could."
