S5: Spike and Buffy both bleeding on the tower, portal opens and two children come out of it...

Hi if anyone could please help me, I have looked but cannot find the name of this fic, it has Spike and Buffy both bleeding on the tower, a portal opens and two children come out of it, a little Elizabeth and William, they are looked after by Buffy Spike and the gang but they have to go back thru the portal to put the balance back right, Buffy and Spike are upset and in the end Buffy is pregnant with twins even though she hasnt been with Spike (done by the powers). Many Thanks

I think the story you're searching for is "Beautiful Disaster" by BittenandStaked...

Beautiful Disaster

Post The Gift. To get rid of Glory, Giles, Willow and Tara open a portal to a dimension that is nothing more than an empty world. As the portal is being summoned Spike is rescuing Dawn and getting skewered in the process. His blood drops onto the portal below and Buffy's blood is on Glory as she pushes her through. What does a portal do when there's nothing to exchange on the other side? Using the blood of Buffy and Spike it creates replicas of them, only when they were 5 years old. Welcome Elizabeth and William...

I'm sorry but I can't post a link... you'll have to search via the way back machine
