It just seems exceedingly pointless to me. If Azazel and Mystique had some epic love story in the comics it might be worth it but to my recollection they had a one night stand and he ditched her right after to go back to his dimension. Because the only reason he had come in the first place was to impregnate as many women as possible. Not exactly a must-have romance in the movie. I love Nightcrawler but since they didn't raise him themselves I really couldn't care less who his parents are in the movie version of him. There are a hundred other way more important and way more interesting stories to tell.
