I'm weeping all over my laptop!
Even if this baby is conceived because he/she will be able to safe Clark's life, when the baby exists both of them will think something like "Really we thought to make our little miracle could be a wrong thing?!" (WEll, I hope they are going to think that!); and iven if now Clark feels himself to be blamed for wanting this child, probably he'll blame himself for not have wanted him/her enough!
Telling Lois about his love is the right thing to do: this situation is already so difficult without secrets!
Perhaps the proposal is a little too much too soon for a startled Lois, but I just LOVE the marriage supposed-without-love-from-Lois stories! Two stories that come to my mind, "First comes marriage" by ML Thompson and "What's love got to do with it" by Missy Gallant (Oh Missy, Where Art Thee?), are two favourites of mine: they are very unlike each other, but both of them are Luthor-related; this is the first I read which is baby's-coming-related, so I look forward to see where this is going to!
