It was a sequel *g*. As for what happened in between, I think there's a scene where Lindsey explains it. From what I can remember, I think Nick and Sara had always been planning to move away from Vegas because it was the only thing they could manage with the baby, and they ended up in New Hampshire (I think). And they tried to have another baby but they couldn't, and they got married in Texas because Nick's mother was dying of cancer.

I don't think there's really much else significant that happened in the in-between years. Nothing I can really think of, anyway.

And you're not harrassing. *g*
