"Very," says Stella. "I have some... boosts. Actually, when Alice turned into a vampire I needed those boosts to not just utterly drown every time I opened up the emotion-blob; vampires have serious mental horsepower. If I'd tried to do without it's entirely possible my ingot power would have decided that mindreading was dangerous and I shouldn't be allowed to do it. Something similar happened to our vampire alt with her daughter. I can give the boosts to Bell too. Actually, Bell should probably just have all the superpowers I do, although it's probably worth explaining them first so she doesn't step off a curb sometime and be confused about why she's floating."
"Shell Bell," says Stella, almost reproachfully. "Of course I can fly. And if I'm not touching the ground and not paying attention, I default to hover, so I don't fall out of the sky."
"You want my design, or your own hex to figure it out yourself?" asks Stella comfortably. "By the way, Shell Bell, these guys get stuff on your say-so, I'm just expecting based on having met the vampire us that you'll be similar enough to me that I can substitute your judgment here - feel entirely free to veto anything." [Including,] she adds, adding Bell to the brainphone, [privately like so and then I'll make up a reason to turn them down on my own.]
Stella squares a hex off her bandolier and tosses it in Tony's direction.
He rises off the floor a little, like a tiny hop without engaging his muscles.
"Awesome," he laughs.
"I think we should have a long conversation about your superpowers," Bell tells Stella seriously.
She explains invisibility, suppressible regeneration, the brain boosts (recall, speed, and capacity), the brainphone, her weather tolerance, the lack of need to breathe, her various defense hexes, spy detection, vision buff, the mess she has made of her sleep "cycle", her illusion viewer, the superspeed, and teleportation. She also mentions several relevant pentagons, most particularly grace.
"One 'all of that' coming right up," says Stella. Hexes go, not that Shell Bell can notice them except by the sudden additions of senses and flexible powers under her control. "Sherlock, what about you?"
"I would like a pentagon with which to achieve masochism," she says, "and the coin power itself, suppressible regeneration, and everything you've done to improve your brain."
"You want to do these yourself? You can still copy mine that way," offers Stella. "That's usually what Alice does when he wants one - although his regen is different from mine; mine anaesthetizes and his hurts all by itself."
