There's a scoop site that I joined in a moment of weakness a couple of years ago that has posted that Natalie will learn she's pregnant after she and John break up. It's a controversial site, and the owner isn't an OLTL fan, but there it is anyway.
Sarahfan I like that idea a lot better as well. She and John have really lost their spark, but then again I never though they had much compared to John and Evangeline. There was just something really interesting about that pairing.
No one ever is ready for a baby but Natalie getting pregnant might make her grow up and stop revolving her life around John. She'd have a new focus, and Viki would have another cute grand baby
