"Alli!" she twines. "C'mere."
"You c'mere. Easier for you."
"No, you need to come look at this, seriously."
"Okay, fine, where are you?"
"Garage."
So Alli comes out to the garage. Their parents aren't home; Charlie's working, Renée is volunteering with some of the refugee kids at a shelter, trying to find which have parents who just wound up somewhere else, which need adopting, which are going to wind up coming of age adrift in the bursting-at-the-seams system. It's just them, not attending school, recovering.
"Whoa," says Alli. "So when you said you were at the garage, you meant that you were at the freakish restaurant that someone put in our garage."
"This isn't somebody's idea of remodeling," Bella says. "It's too big to be the garage."
"Do you think it's safe?"
"I think one of you should go in first, for sure."
"We don't actually know if I work that way," say two Alli voices, but Bella pushes one of them towards the door anyway.
Nothing happens.
The Allis converge, inside the bar. Bella follows.
"We don't bother with secret identities almost ever. We'd have to conceal our ages or sisterhood to avoid being known as twins, and our powers are so useful for everyday that hiding those so as to be unrecognizable in masks would be a tragedy. I am glad you are not reading my mind. Continue to never, ever do that."
"Wasn't planning on it. We don't have secret identities in our home world, for various reasons, including but not limited to having to be in the closet being tragic, but it's useful where we're staying now. Mostly because for cultural reasons unmasking is a big enough deal that if someone can threaten us with that they're less likely to try to threaten us with something else."
"Funnily enough, due to shenanigans I'd rather not get into, we did have to conceal our sisterhood for a while."
"Milliways pauses time in your homeworld while you're here, so when we go back we won't have missed anything. And we owed this guy a favor, so he asked us to fill in on his team for a while while he got someone else who would fill a similar role. And I get doors pretty often, so it's not too massive a risk."
"I know, right? I get fruity beverages made of fruits that don't exist in my homeworld, it's fantastic."
"We're not totally frivolous! We bring home fantastic medical technology to have reverse engineered."
Objects made with engineering are merely a matter of arranging matter correctly. I lack the qualifications to perform any kind of magic beyond what I use to create things at all, sense my environment, and think.
"She also won't give you weapons--as I referenced when we first came in--living things, or anything bigger than her."
"I see. And anybody lucky enough to find you has just encountered El Dorado...?"
After the first beverage I do charge reasonable currency-dependent prices.
"Gotcha."
"Also if you get up to the kind of behavior the Conquistadores were so fond of she has a security team guaranteed to be a match for whoever's in the bar at the moment."
Her drink recommendation is hot chocolate. With whipped cream.
"So, we don't do secret identities, but we do code names. I'm Flicker and she's Verge."
