See, the thing I liked about the Kesel Hawk and Dove was that they DIDN'T seem to love each other, at least romantically. They trusted each other implicitly, and were as close as brother and sister, but they were the sort of opposites that wouldn't be that interested in each other in a relationship. Plus they were both slightly freaked out by the fact that any romantic feelings they might have might be residual echoes of the Lord of Order and Lord of Chaos who empowered them (and who HAD fallen in love) rather than anything from THEM.
Armageddon 2001 showed them having a child together in the future, a girl who embodied both Chaos and Order with the "magic-name"; Unity, but in the present Hank had Ren Takamori, and Dawn had Detective Arsala (Who I STILL get steamed about the casual murder of to show that Monarch Hawk was badass in the... no, I shall not revisit the mess at the end of Armageddon 2001 AGAIN!)
