"You can say whatever you're thinking, I won't be upset.  And it might help."

She curls up tighter and squints at him. 

Then, slowly: "I don't want to not be okay."

"Don't reckon anyone does," says Hagrid gently.  "But sometimes trying too hard to be okay makes it worse."

"...Dunno."

"Well, I won't tell you how to feel about it," he says.  "But if you ever want to talk, you can send me an owl."

"...An owl?"

" - blimey, I'm sorry - it's how wizards send letters to each other, magical owls.  Most everyone has one by the time they graduate, and Hogwarts has a flock you can borrow from."

"Do they carry the letters?"

"They do!  Tie 'em right to their legs.  Right smart birds, owls are, 'specially magical ones."

"Huh. I've never met an owl."

"You'll get plenty of chances at Hogwarts.  First years are allowed their own, too, if you want."

"That seems like - a lot..."

"They can take care of themselves all right," Hagrid says.  "But you don't need one either.  Hogwarts has a flock, and even out of Hogwarts, there's rental owls."

She nods, thoughtful.

Healer Pendleton returns, and Hagrid lets him back in after checking there's nothing else Harriet wants to talk about in private.

"This," he says, and hands Harriet a pointy, wide-brimmed black wizard hat, "is for your light sensitivity.  It'll cast a shadow over your eyes that adjusts for how bright it is around you.  You should be sure to put it on any time you go out in the sun or any time your eyes hurt.  Nothing wrong with wearing it around all the time, in fact, but you can take it off if it's not too bright."

She takes it, turning it over in her hands and then plopping it on her head.

"Thank you, Healer Pendleton!"

He grins.  "You're welcome, Harriet.  I also have a couple of potions for you."

He produces from his pocket one small vial, big enough for perhaps one swallow, of some silvery liquid, like mercury with a concave meniscus.  "This is your first dose of Elixir.  Now, you're a bit behind on your dosage, since it took so long for Hogwarts to find you, so you'll need to come back every three months for the next year to catch up.  You should drink this one now."

She takes it and drinks it, obedient. "How will I get here?"

It tastes like quicksilver seems like it should taste like before you learn it probably just tastes like metallic poison.  "Hogwarts is connected to the Floo network.  They'll be able to make arrangements for you."

She nods. "Okay. Thank you."

"You're welcome."  He produces a second bottle of potion, this one larger, stoppered with a cork; and a little metal spoon.  "This is your Benourishing Potion.  You should take one spoonful of it with dinner every day until you run out.  If you take it on an empty stomach it can make you feel more full than you actually are, so it's probably a better idea to take it after you've eaten."

"That makes sense..."

He smiles again as she takes the second potion.  "And these," he finishes, producing a trio of little vials like the first, each half-full of something sky blue, "are something you can take just in case you do have a bad reaction to something in the Benourishing Potion.  It's not very likely that you will, and even if you do it's not very likely that you'll need these, and even if you do need them if you take one and get Mr. Hagrid or somebody to Floo you to St. Mungo's you'll be fine.  But it's best to have them on hand just in case."

Slow nod. "I just drink them?"

"Just one of them," he says.  "Best to have a couple spares, just in case."
