"There's lots," says Glass. She peers at him. "Oh yeah, that's - about as attached as you get, these are not optional."
"And the - template we don't have a name for -" (Glass waves at Keth) "are the 'leader' template here, except that's less meaningful than it is in some cases because you're just always going to appear together, one for one. Oh, wow, you are so attached, but apart from always showing up in the same place it's almost totally unidirectional... Also I think everyone should be glad there aren't a set of you in Aurum, that would get potentially gross very fast... Thilanushinyel could do the same thing, come to think of it..."
"Oh, Kingfishers, that works. The gross is potentially unreciprocated eternal bonding. Aurum has two kinds of it, and if you landed there..."
"The Rayne in such a world would inevitably wind up stuck on the Kingfisher, and there isn't a shred of metcausality enticing it to be all sewn up the other direction. Metacausality has no interest in making sure Kingfishers like their Raynes, the Raynes have to do that themselves."
Keth smiles at him. It is a smile full of communication not meant to be intercepted.
"...I - huh. Can your daemons come out where I can see them?"
Glass peers at them. "I think they're helping you with the not-having-a-falling-out. They are, however, not a guarantee."
"Anyway, I think that's all I have to say unless it ever becomes worth everyone's while to collect the other three Raynes and line you all up."
Glass snorts. "Back whence we came?" she inquires of Keth. "Or is there anything else I should look at while I'm here and already covered versus flying squirrel?"
And back they go, right where they came since Pattern is still there. Glass relays the information.
