"Oh?"

"What's your name? I'm Serpens Malfoy."

"Harriet Evans..."

"Like Lily Evans?"

"Yeah! She's my mom. Or was... Mister Hagrid said she was really cool."

"She's certainly famous. I didn't know she had any kids..."

"Mister Hagrid said Hogwarts couldn't find me until recently, so no one knew I was alive. Except the Muggles, I guess."

"Huh. Maybe your mother hid you."

She picks at a loose thread on her shirt, then stops when a tape measure chides her. "Maybe..."

"Hogwarts is going to be more interesting than I thought."

"Really?"

"Oh, yes."

"You know, your mother's the reason my father's in Azkaban. That's a wizard prison, the worst of the worst."

" - Oh! I'm sorry. That must be terrible..."

She stares at Harriet like the other girl just sprouted a second head. Or perhaps turned into a very interesting puzzle.

Harriet fidgets, feeling much more awkward than she did earlier.

"You're weird," she says.

"...Prison's bad..."

She snorts. "It's fine as long as he doesn't get out. He'll be raving mad, then, and probably out for blood," she says, cheerfully.

"...How is that fine..."

She grins and says, "I think we'll get along swimmingly," before jumping down from the stool as her own tape measures finish their work, waving to a woman who's just entering.

"Mama!" she calls, brightly.

"Hello dear," she says, before turning to catch Madame Malkin's attention (and, incidentally, Hagrid's).

There's a much shorter blonde girl peeking out from behind her robes, mostly staring at Hagrid.

Hagrid returns to Harriet's side, perhaps a step closer to Narcissa than Harriet is.  "Mrs. Malfoy," he says, evenly, nodding to her in curt greeting.

"Mister Hagrid," she says, barely nodding back, voice also curt.

"Got what you need, Madam Malkin?" Hagrid says.  "Going to be staying at a room in the Leaky Cauldron, I'll owl you which.  Can have the robes sent there."

(Madam Malkin - nods.)

Narcissa turns toward Serpens. "Everything alright here?" she asks.
