[Jane?]
Jane... pretty much fails to exist.
[Jane.]
Nothing.
Bella goes to the Janepoint, and there's a message for her on the screen, something about lost ansible connection.
Well, shit.
[Queenie, Ghosty, Slipstick?]
Bella proceeds with her usual activities, evades when miscellaneous world leaders ask if she had anything to do with the thing in Gotham, and checks on Ganymede the next day.
Ganymede is extremely orderly. Bane stands guard by the food replicator, and ceremoniously allows any who approach to operate it and take their food away in peace. They have already begun a collection of nourishing non-perishables close by, and everyone who gets food from the replicator to eat right away also contributes to the stash.
Off she goes, then. She figures she'll let them go a week before she installs, say, houses and flora without being so much as shouted at for them.
She's not sure whether this is for fear of peer reaction of some kind, so all the houses - there are enough for everybody and then some, if terribly samey ones, each with their own plumbing and replicators, arranged in a circle - can be locked from the inside against any non-teleportative intrusion, and include little fact sheets (in the reader's native language, whatever that may be) to this effect. They are invited to summon her by folding up their fact sheets, along existing folds; if someone secretly wants to talk to her they have every chance, now.
She spends most of her time curing diseases and convincing various prime ministers of this and that that she's here to help, but periodically she drops in on Ganymede and adds amenities - ground rules, a library (no Internet, not till Jane's back). On a whim she decides to give them a swimming pool. It's not like unfriendly possibly-cultists are liable to be the only people she's ever going to need to put out of the way.
That's better than the alternative. Bella checks in once weekly like clockwork, by pastwatch often as not, and otherwise goes about her business.
