How long will it last? Until DC liberals decide to change it. DC is just like Star Trek and other comics. Relationships work only to a point then it comes time to change. How many DC couples have lasted more than a few years before someone dies, differences tear them apart or we get some universal restart? All the GL's? Hawkman? Swampthing? Flash was on and off. Atom? Now the rewrite of Alan Scott throws his out the window. Shall I go on? Personally, I thought the two would be good together (see Kingdom Come) but in the DCU, I'll believe it when I see it five years. Long term, couples just do not make for good stories and this one? What story lines are you really going to have about the "super couple" that's going to be THAT interesting?
