Bella tries to get out of the letter-named-rooms building to go ask Emily for directions, but that's not a stairwell after all, and there's someone shouting at her not to come in and she flinches back and clonks her elbow on the door and boots or no boots she's down and she -
- is falling -
"It won't make you use them up, although it won't make them come back any faster either. And testing magic is dangerous so I'm going to do it in case I explode or something."
"I don't really want to explode either, but I also don't want you to explode, and I'm only allowed to teach you safe magic."
"I suspect you are not allowed to give me the kind of leave I had in mind, although of course I wouldn't teach you anything if I didn't have your personal permission to do that. And I prefer you to definitely not explode."
"That would be really surprising, and I can't teach you everything anyway so I will have to live with that risk."
"I don't know if you've already cast it as many times as you can or not," she shrugs.
...Bella sets the arcane mark scroll back on the desk and picks up where she left off when she went to bed.
She finishes the scrolls she knows, all sixteen of them. She puts them in piles, one with the sound spell on top and a note saying not dangerous and one pile with a note saying dangerous!, just in case Fëanáro wanders into her room later and decides that the best possible next action is to decipher a scroll having learned to read exactly one; at least it can be arcane mark and not acid splash.
And then she goes out to make some progress on her house.
Cool! She makes inquiries about the indoor plumbing thing and decides she wants windows once plate glass has been invented and shows her floor plan to relevant persons.
She thanks everybody... sifts through her presents again and gets them all out of the way of construction... and heads back to the palace.
He charts a mental map through the palace. She's okay. She talked to Finwë and he said he thought you'd already gone to Lórien and then she sort of relaxed, like if it couldn't be done it was okay that it wasn't, and told him she wanted the memories back so badly and he promised she could have them back in a month and keep them if she then desired. And then Fëanáro came and is now reading to her and they are very much not okay but she looks alive.
