Blake is a Rook but somewhat secretly shares a lot of the sentiments Natasha has. I would love for them to either have a standing relationship where they subtly and quietly gripe about the social plateau, maybe bemoan a little the speed at which things change (or don't). He could even try to take off some of the wedding planning pressure by being uncharacteristically decisive on opinions about the plans.

I think it would be neat to kind of start out as smirky "old friends" that are both in over their heads with Parliament, but also pretty stubborn about giving up their morality.

Also open to other options as you please, or just handwaving some stuff to be followed up on later. o/
