"Well, Hogwarts, o' course! Professor McGonagall was very confused when we got yer letter. Yeh said yeh didn't know how ter get yer things there, but yeh sent it!"

She winces. "I met one of the owls as it was delivering the third letter. I sent my reply that way."

"Third?"

"Well but why did yeh need to. Didn't yer aunt and uncle take yeh ter Diagon Alley when yeh got yer first letter?"

"They didn't see the first or the third letter. I don't think they would have been open to talking me to Diagon Alley if they indeed know where that is."

"...yeh don't know? Ah, o' course not, these muggles wouldn't—well, but they know how to send these letters back, no?" he asks, looking at Uncle Vernon.

He glares at the giant. "All these years, we swore we'd stamp this out of her, we won't—"

He's interrupted by Hagrid's guffaws. "Stamp it out? Of Sarah Potter? Are yeh mad?"

"It said that you expected an owl and it didn't have a stamp on it so I guessed that it was also delivered by owl, and after the second letter I expected there might be a third."

He nods. "And what did these muggles tell yeh ter convince yeh not to go ter Hogwarts?"

"They haven't told me anything about magic. Everything I know I figured out myself."

He blinks a couple of times.

"But yeh must know about yer mom and dad," he says. "I mean, they're famous. You're famous."

So the story the Dursleys have told her about her parents being lazy drunks who died in a car crash was as wrong as she thought it was. "They haven't told me much about my parents. I wasn't aware they were famous."

"DURSLEY!" He explodes, turning to look at them and causing Dudley to squeal louder and run upstairs. "So yeh've never told her nothin' at all? Never told her what was in the letter Dumbledore left fer her? I was there! I saw Dumbledore leave it, Dursley! An' you’ve kept it from her all these years?"

"STOP! I FORBID YOU!"

"I don't think yelling is helping matters Mr Hagrid."

"But they—they never told yeh—never—yeh don't know anything'!"

"Magic is not the only important thing in the world."

"Well—no but—yer parents, Sarah! Yer world!"

"I'd be happy to have you tell me about those things."

"I said and I repeat, I will not be having any of this nonsense in my house!"

"Aye, yeh big prune, yeh won't, 'cause Sarah's learnin' all that at Hogwarts not here." He turns to Sarah again. "I can't teach yeh ev'rythin, that's what Hogwarts is fer, but I can tell yeh some things."

"I'd be happy to hear whatever you feel capable of explaining. I've mostly only done magic by accident and I can't seem to reproduce the things that happen by accident."

He suddenly looks much more anxious and subdued. "Blimey, I never expected this," he says, in a low, worried voice. "I had no idea, when Dumbledore told me there might be trouble gettin' hold of yeh, how much yeh didn't know. Ah, Sarah, I don' know if I'm the right person ter tell yeh—but someone's gotta—yeh can't go off ter Hogwarts not knowin'." He throws a dirty look at the Dursleys. "Well, it's best yeh know as much as I can tell yeh—mind, I can't tell yeh everythin', it's a great myst'ry, parts of it..."

"I don't know what you're referring to, I can always learn more details later."
