I have been rereading the comics and watching the show lately and saw something interesting. What I saw was that with babies that are either coming into the series or already in it their fathers are dead. I mean this is a very little thing to notice but there is Judith having Shane dead (even though it's only a possibility he is the father). Then there is Glenn who is about to have a kid in the comics but he is dead.

Why I really bring this up however is because Omid and Christa are about to have a child. So if this is a theme then do you think Omid might die like right before the child is born? Just a meaningless speculation though that I wanted to throw out.
