"Yeah, when 'Tony' and 'Sherlock' don't cut it, I'm Screwdriver and she's Pearl," says Tony.
"You're a me? Wow, you're totally a me," says Tony. "Um... what if I can't think of a good nickname?"
"None of them could," says Shell Bell dryly. "They wound up deriving ideas based on their coin colors."
"Ooh."
Shell Bell makes a square of her own, shows it off, and spends it to produce illusion coins in the princesses' colors.
"...Red-hot iron, apparently," says Tony. She peers at Sherlock, and laughs. "And you're steel. Is there a Steel?"
"Any ideas on how to turn yours into a nickname?" Shell Bell asks Princess Tony.
"I guess you could go by 'Princess' for now? It's not perfect, you wouldn't be the only princess at a Bell party, but I think it wouldn't be that hard to keep your family and Elspeth straight, and if you can't think of anything else..."
"So you're all blacksmith fire-witches who make flying armor?" says Glass skeptically. "Granted I don't know how to turn any of that into a nickname..."
"Blacksmiths not so much - more engineers - low-tech here? - and what is a fire witch - and yes on the flying armor, Iron Man did that."
"A fire witch is a kind of hereditary magic user, mostly having to do with fire," says Glass. "One married into the royal family a few generations back. It's a little thinned out for my wives. The little ones can handle hot things safely - Carinna likes to play with hot glass - but that's all."
