Although I do like Vera and Cillian as a couple, I also wish InCase wrote an alternative chapter for Cillian and Nadia. It's unclear if serpent women have to find new partners all the time or if they just need to have several spouses instead of only one. Let's say, Cillian had found some sort of a multiplying spell and had created three or four copies of himself, that would have solved their problem perfectly well. They would have a polyamorous family while actually staying monogamous.
@Ermanarich, from the way he tells it, it sounds like they either don't get married or they have--very--open marriages. I really like Vera and Cillian; it's a good counterbalance to Alfie's story, which seems to be mostly her making bad decisions and the people around her treating her like shit.
