It is culturally coded as a bit silly.

That is not a drawback.

Some people find it to be so!

Here we might start a war but no one will find us silly.

Let's hope it doesn't come to that.

Yeah. 

Ugh. People: why.

Uh huh. Let's do the boat first.

Yeah. Know anywhere we can get a fuckton of magnetically responsive metal without it being missed?

Not really - they're probably demolishing buildings somewhere but I don't offhand know where....

"Would it be on the internet?" Ruby asks.

"Where they are demolishing buildings? I wouldn't know where to look but maybe?"

She closes her eyes and frowns in concentration. After a few minutes she rattles off a handful of addresses.

" - okay. Cool. Uh, maybe instead of flying we should take the train, attract less attention."

"Even when we can be invisible?"

"Or you could be invisible, that works fine."

"Is there roof access?"

"If we pay for it, yeah."

"You have to pay to go on the roof?"

"Yeah? Otherwise it'd be really crowded, this building is a hundred thirty stories."

"...Huh. I don't think I've ever been in a building that tall before. D'you have the money for it, it's easier to take off from higher up."

"I can afford it. Are you carrying me or am I taking the train."

"I can carry you! ...If Emily takes Ruby. Or she could carry you."

"You have magic super strength?"

"Comes with the wings."
