There's something very nostalgic about standing in front of a large audience and walking them through scrolls and then expounding on the principles of magic. She has more to say at this point, though, she's dissected more spells into their component pieces and Olórin's been around for a while now to help explore vast combinatorial explosion.

Cling! "That's a good explanation! ...I'm indestructible now, it'd be safe for me to actually have wings, right?"

"So then I could just have wings and I wouldn't have to explain why I don't have wings."
"You will in fact have to size up a dozen times," Cam says. "And replace half your wardrobe, and you wouldn't be able to look normal in Elf or human contexts."
"I'd look like a demon. I really wish I were a demon. You get to help so many people and do so much amazing stuff."
"Well, I could still do all the things I'm doing if I were a demon and also I could make anything anyone needed."
"You can't summon if you're a demon," Cam says. "I suppose you may not be doing a lot of that."
