They perform some more magic tests and run out of mana and recover mana and perform more tests and a second sleepover could be fun but it's decided that people can do coordinated tests in their own places and there is not actually a need for them to all be in the same place. The Maxwells' driver takes Jess home (and Maya, too, if she prefers that to staying with the Maxwells but they assure her she's welcome to stay there), then takes Sadde, Theo, and Tyler to the Farron residence, where Sadde prefers to be dropped—he'll go to his place by public transportation, he'd like to talk to the—twins?—yes, thank you, it was a pleasure meeting you.
"Would it do same as at the house, lock the whole bag magically and not just strengthen the padlock?"
"I will look into getting a padlock then," he says. "Any chance the Shadow conceptually does stealth, or the Glow does – attracting attention?"
"I mean, you said they have – sort of domains, if I recall correctly? You can use some cards to do things they're not directly of, though they're not as good as specialised equivalents."
"Oh. Right. Hmm, I don't know... You can use the Shadow to affect things remotely, like through glass or something... But I don't know about stealth."
So Theo gets the Shadow out of his bag and then says the annoying phrase to turn the key into the stupid pink staff and then – "The Shadow, I command you to aid me in stealth."
He looks at his hand.
Is he at all hard to see or would this only be helpful at night?
"Works for if we want to sneak around at night," he says, and wills it away.
Theo swaps it for the Shadow anyway and asks that it try to make him seem more noticeable.
"And – the Twin won't work on cards, apparently you said it doesn't work on magical objects? Do you know why it works on magical people?"
