When Fëanáro is feeling sociable she hangs out with him. He finishes his novel. (In it, the school turns him over to social workers and adopt him out, he escapes his foster family, he encounters a dragon and talks his way past it with stories about Arda, he studies wizardry and is unreasonably effective at it, when the dragon opens a portal to Arda he sneaks through too and the Valar slay the dragon, he fixes his mother with magic, and then he masters planar travel himself and conquers Bella's plane.) He finishes his typewriter, too; Bella's of the opinion that it would have been easier if he made vowels separate instead of consonant-hats, but it works okay like so. She acquires one when there is more than one, and learns to type, because crystal balls are a long time coming.
She has made some progress, though. She finds the common thread in dud combinations that produced an aura, and successfully decomposes all her original spells into pieces and begins to make new combinations. Most of these are trivial like the increased character limit arcane mark. Reverse-engineering her undead-damaging spell, though, gets her (small) arcane healing well in advance of when she was expecting to have that down. So anybody who lives on her block and cuts themselves cooking breakfast can knock on her door - or that of anybody who's getting the spells as she turns them out - and get that seen to without bothering a Maia.
Once a month she sees Miriel. Bella doesn't have any ideas that land any better than "forget you forgot something". But forgetting the contents of that foolish, foolish oath is at least a holding pattern that lets Miriel pretty much live her life, so, therapeutic success? ...Bella makes sure to remind Fëanáro that he is very adorable and lovable and adored and loved.
Bella looks at her watch, goes and sits with them. Hey, she says, so as not to interrupt the epic.
"I'm not here to stay, I just came by for Miriel's appointment. I might sleep in my house, I'm not a hundred percent sure I won't run out of mana and fall into the sea if I fly all the way back."
"I couldn't get the duration long enough if it was one-time expenditure and I didn't want to have to re-cast on the way. And you too."
"Oh yeah, much. The mind shield spell to ward off the time slidey thing is really complicated so I'm not seeing major returns on that right away, but when I pick something more conventionally doable as an interim project I'm blazing through it. Fëanáro, if I teach you to fly are you going to try to fly to the island?"
"...okay, good, because I'm not sure you have the mana for the whole trip and it would upset your parents."
"I've been practicing longer and sleep more often so I can practice more frequently too."
"Oh, if I'd known you wanted to fall asleep I could just do that for you, when I was around more, I thought you just liked being awake way too much!"
"Well, when I'm back full time we can invent a spell for it or I can just put you under by arts."
"Five minutes won't do it but like three or four hours will probably get you to at least half capacity."
