>>29065156You have an opportunity to give the two the opportunity to jockey with each other over philosophy, as they both follow different approaches to how things should be handed - Steven leaning on pragmatism and Zinnia on intuition. That can manifest in a variety of contexts, from how they deal with minor villains they happen across, how they solve problems that manifest with their journey, and how they manage their time doing research as they move from town to town.
For that though, you'd need a reason for them not to always be splitting up and saying, "Well I'll go to ____ and you'll go to ____ and then we'll just discuss what we found," because that would get stale.
How this villain gets dealt with also becomes a point of their debates, as I'd imagine that they both would have differnet ideas about how they're going to deal with this guy once they finally find him.
This all has the effect of creating a space where both sides of the argument are presented and deliberated on, and you can tailor the work to suit whatever philosophy you feel is right - or set the work to never provide a "correct" approach, only different manners thereof.
'Course, if none of that really floats your boat or is what you had in mind, I wouldn't say no to tried and true opposites-attract romance.
