What makes me sad is thinking of what other writers would have done if told to create 2 children for alternate versions of Kitty and Colossus. Claremont would have given them original names. Most others would name them after their actual family members. And most others would do something creative with their powers instead of just making them carbon copies of their parents' powers. They're most likely going to die before they get a chance to show any personality, and even if they live longer than expected, will still likely have no personality put into them.
