Then again I am naturally drawn to characters I think might be polyamorous or bi or demi or even omni. Bonus if the fandom ignores, bashes or holds them to a higher standard because they're: female, queer, gender (non-)conforming OR not white (namely Black).
But maybe this is also an inner expression of myself as bi woman with poly tendacies. As I grew up rejected and abused, I tried to remain open--expand with love energy in an attempt find anyone who would love me just as much as I could love them. Of course when you try to stay open and pure hatred lashes out at you, you want close up and shrink away, nurse a broken heart and try again. Not try for the person that rejected you. No, never. But this reaching out with love energy is like a signal looking for a good wifi receiver.
So with characters that are ignored, I guess I imagine them reaching out for love and acceptance where available in the way that I do. John Green never struck me as canonly reaching out for those things, but I'm sure he'd appreciate them be they from any or no gendered folk. And I like the idea of him with Flash and Hawkgirl... either as cocurrent relationships or an equsl triangle.
Fanon, canon--whatever. It all gets mixed up in my head and builds even more interesting characters.
