But she can't see anything till they show up.
Cam arrives first, despite having been a later addition to the expedition - no one was distracting him with last-minute goodbye makeouts - and she clears him and he waits around for Jellybean.
(The Joker also arrives, with an arm wrapped around Jellybean's shoulders and his nose pressed into Jellybean's sugary-smelling hair. Mmm.)
The aura doesn't appear to care about Nathan's air filter.
Nathan is making confused noises, and he's trying to bite Jellybean's neck open, and it's not working very well.
"Your aura, withdraw your aura," exclaims Alice, scrunching her eyes shut.
"That was by far the weirdest sensory experience I've ever had," he says. "Sorry about that."
"You could get thirstlessness like I did," Alice says. "It's more comfortable anyway."
"No thanks," says Nathan. "I don't think many people are going to show up all synaesthetic sugar that bypasses my air filter, and sometimes I want to be a little thirsty. Right, babe?" He winks at the Joker.
"Well," says Cam. "That's an interesting... welcome... we got. I guess now I know what your aura does, huh, Jellybean."
"I don't see anybody mating to you, anyway, Jellybean," says Alice. "So you and Cam are both clear to move freely around Aurum with standard cautions about not revealing magic to random humans and so on."
"Cool. I'm gonna go chat with Golden and see if her husband can in fact behold me without being as disturbed as he is by girl Bells," Cam says, and he teleports away.
"I assume you can actually let me bite you?" Nathan asks. "Trying and failing while desperately wanting to, not my idea of a great time."
Nathan spreads his arms in a display of readiness. "Rar."
Nathan is in no condition to appreciate the fine details of his bouquet. He's just biting and growling and swallowing.
He takes a step back, inhaling deeply. "Wow."
"Tasty," Nathan says. "Intensely drinkable. Massive sensory head trip. Did the vampire one of you guys get his teeth into you?"
Nathan laughs. "Well. Welcome to Aurum."
"Addy almost certainly. Let's see, who else... not the Imperial Family, I don't think, except maybe Emmett or Jasper, but plenty of the staff'd probably take you up on it."
