"I got it, Elspeth was pretty thorough," says Tab. "Jane's an accidental AI who basically works for the peal of Bells. She's broken now, but when she works she does at-will interworld transit and eats Internets. She can avoid parts of them - she hasn't bothered the various Jarvises, who are non-accidental AIs who are attached to another template we don't have here - and I think she'll need to steer clear of a few things here, too. But there's no harm in just having a gem that connects up to her Belltower hub so she can talk to me if she reappears."
