"Okay, but, like - Angela's pregnant. They're probably going to have a bunch of kids because of angel cultural stuff, let's say it's six. And based on what we know about how templates work, that's a very good piece of information for all the other Bell-Joker pairs about how they'd have kids if that happened. I bet Jane doesn't count, although if Angela manages to have a little winged biological Jane I will be super impressed with template attractors, like, as a force in the multiverse. So say Rose meets all of Angela's kids and she doesn't get along so great with kid number three. And say that Rose would've had three kids, but decides to stop at two because she doesn't like Angela's third kid. I think that would be a good thing for Rose to do, to stop at two, even though somebody who presumably likes existing doesn't get to exist a second time. I think it would be good for us to warn a standard Renée and Charlie. But they could decide from there."
