Superhero weddings are never easy whether it's in comics or in live-action. The Flash Season 4 has promised that we'll see Barry and Iris finally get married this year. <P><P> It will be taking place during this year's 4-show crossover titled Crisis on Earth-X. Because what would a superhero wedding be without evil versions of yourself as Nazis from a different universe crashing the party? <P><P> I'm still not over the fact that Clark Kent and Lois Lane's wedding on Smallville got crashed. That wedding got ruined because of a Darkseid-possessed Oliver Queen/Green Arrow. <P><P> I guess it could have been worse since in this crossover, a bunch of Nazis will be the party poopers. Even if they have to a do-over later in the crossover, I want the wedding to still feel spectacular. <P><P> That shouldn't be too much to ask for the most iconic power couple in the DC TV Universe, right?
