I'm plotting. This is kind of a constant for me, and also a great answer when someone asks me what I'm doing, because most people don't expect that response.
Plotting character interactions is, for me, one of the more difficult parts of creating a story. Characters grow and change over the course of plotting, and even more so during the actual writing, so no matter what I start off thinking they're going to do, there's always the chance that they'll do something else. This usually happens right in the middle of a sentence that I swore I knew how it ended when I started writing it.
Ever stared at the page and asked someone "Why are you running toward the dragon, you're supposed to be running away?" Yeah, it's like that.
This gets worse when I think two characters will end up getting together over the course of the story. I think we've all read or watched a romance that only happens because the writer said so, where everything seems awkward and forced and it's hard to imagine these characters actually getting together, let alone staying together. This gets even worse when it's the last chapter/episode/five minutes, and whoever's in charge just wants to end the thing with a kiss and a happy couple.
Hands up if you can name at least one book, movie, TV show, or anything else where you've seen this happen. No, I can't see you, but I doubt I'm alone in this.
When I was putting together the ragtag crew of characters for this story, I thought two of them might end up romantically involved, because it fit their personalities, and it could be awesome. But it was also the first time I'd written these people, and they're not only from vastly different backgrounds, they're from entirely different worlds. They're not even the same species, though both are sentient humanoids (sort of, one's literally only half humanoid). So I had my doubts.
I don't think that every story needs romance. There's always room for it, but it's not essential. And the last thing I want to do is force two characters to get together.
One of the downsides to being a plotter is needing to know what's going to happen in order to write a story. I'm always open to change, but I have to know how things end. This includes character arcs. So, what could I do about this might-be romance?
It turned out to be easier than I thought. I wrote up as much as I could about these characters in my notes, and plotted their interactions with all that in mind. I let them bounce off of each other, considered how they'd react to all the things that get in their way over the course of the journey, and waited to see if the events and their conversations and all the little differences between the two of them would bring them closer together.
Will it? I'm not saying. I have to write the damn thing first, and I think I've made it clear already how much things could change before the story ends. But I know how I think it's going to go. And that's enough for me to get started.
