This suggests that two versions of the same person from the same universe, Clark Superman Kent, is physically present in the same time frame. A four-year-old Kal-El is going to meet and perhaps shake hands with his tweny-nine-year-old self. Back when I was reading science fiction, I was often told that two differently-aged versions of the same person can't exist in the same time frame.
Not that you have to obey any of these rules, Mercy. After all, what do those science fiction people know about time travel anyway? For that matter, what does anyone? To my knowledge, no one has ever traveled back in time in real life, or jumped ahead in time, either. I'm fine with you making your own rules, as long as I understand what your rules are. I didn't at first, which is why I was confused.
Ah, but let's get on with the story, shall we?
