Well, he's got enough info here to go see whether anything can be accomplished by talking to the site manager. Did Carissa want to be with him for that? It's not obvious that Ione/Asmodia/Meritxell need to stick around for that, they are free to depart if they so will.
(It's not clear that, besides Asmodia having her contract on hand, those three really needed to be here either. This whole conversation didn't end up going the way it would in Civilization, what with, say, equity not really existing. But Keltham would've felt pretty odd about it if the tier-1 cofounders hadn't been called in by the tier-0 superfounder for at least this much consultation.)
