Speaking as someone who hasn't seen the episode that this fic is based on, I can imagine adult Clark and Lois keeping four-year-old Clark and raising him as their own son. Wow, that would certainly be a reason for Lois and Clark to get married in a hurry. They would have to say that Clark, who is himself adopted, had managed to trace a biological relative of his, only to find that his relative had suddenly died and left a four-year-old behind.
Wow. Talk about time travel conundrums.
