A long time ago, we had an Endometriosis challenge here on the boards wherein Lois had to get pregnant in a hurry. Lately, I got to thinking...
What if Clark learned he had a limited amount of time in which to get a woman pregnant?
S1 or S2, of course; otherwise, it's too easy.
So! Who will the prospective mother be? Will he try to rush to the altar, or get out the turkey-baster? And most importantly...Clark Kent or Superman?
