In the next book I’m pretty certain… it’s about all of their kids when they grow up. Although a couple of the relationships are pretty messed up if you think about it even a little (noah’s coworkers are around his kids their whole lives and end up getting romantically involved with them when they’re of age.. and it’s something that’s not considered a typical relationship dynamic even in their universe,,) but if you can tolerate it or just skip those chapters, their youngest son ends up with him

Him wanting triplets is pretty funny when I know they end up having one sickly child
