Ironic, since Seed Destiny wrecked most of the couples from Miriallia X Dearka, all the way to Athrun X Cagalli and that was the most stable relationship at the end of Gundam Seed. The only surviving couples are Murrue X Mwu and Kira X Lacus, though the latter never seemed to be the most stable. So...that's my bitching.
On another note, regardless of how awesome other Gundam series become, Gundam Wing will always stay near and dear to my heart as my first Gundam series. I don't care if it doesn't have the most advanced technology or about all its flaws, it is still one of the best AU series made and PROPERLY paid tribute to UC without being a complete ripoff, considering that Zechs broke the mold of typical Char clone into his own likable character.
