My OTP has two kinds of canonical interaction: antagonist, and tragic. Moreover, neither speaks of the other except to relay plot-related, important information. So, I think I'm a little crazy, because how I view them interacting is based entirely on my perception of their characters. From peeling away their layers and writing them interacting based on what I can pull out of canonical information. Not anyone else. No one else I know of has come to the same conclusions about them that I have. Generally, Caius and Lightning are viewed through one of the following lenses in the fandom: 1) rivals and little else, 2) Caius being a lust-filled villainous type who only wants Lightning for sex, 3) them coming together intimately solely for hate-sex or pure lust, or 4) some sort of disturbingly dark romance that may ultimately have no romance at all.
As far as I know, I am one of the very few who sees how the vulnerable sides of them can mesh and how their journey can bring them together. I'm not saying I'm right, but I'm wondering how I came to that conclusion at all. I almost feel alien as a result, like some weird outsider in the fandom. Two rivals whose only non-antagonist interaction was heart-wrenchingly tragic make up my one true pairing. I don't understand how I came to that conclusion, now that I think about it. Am I making stuff up? Am I seeing stuff that just isn't there? Am I crazy?
My beliefs tell me no one is beyond redemption, while Once Upon a Time and Tumblr metas about it taught me how a good romance that would normally be terribly cliched can be done well. That doesn't properly explain, though, how in the heck I came to the conclusion that Caius and Lightning, whom I started shipping when I saw XIII-2's announce trailer in January 2011, could ever have a healthy romantic relationship.
