"Okay, but don't get too involved in anything," says Shell Bell. "It's traditional when we find new Bells to throw a party!"
"It tends to depend on how closely spaced the parties have been. The last one was when Jane came back online and that was a couple months ago, so we can expect a majority of the invitees, coming up on ninety people, one of them is a dragon. If you don't have a good place to put the party someone else will be happy to host. Not everyone's gotten a turn yet since by the time we threw the first Bell party there were already eight of us."
Meanwhile, Carinna has decided that Grandma should know about these extra children she has acquired. "Graaaaandma!"

"Is this becoming a family thing? This looks like it might be a family thing. I can leave."
"But then I'd have to explain all the new magic details to you separately."
