I read a story a while back where Olivia asks Elliot to have a baby with her.
I don't remember a whole lot from the story but I know that Olivia was on the roof of the precinct when Elliot asked her what was wrong and Olivia asked him if he would help her have a baby… after thinking it over Elliot agrees so they go to a clinic to do artificial insemination and are supposed to go back the next day to do part two of the procedure when they get a phone call saying that the clinic burned down. So Olivia convinced Elliot to do it the old fashioned way… Just sex. It works she gets pregnant and then they find themselves starting to open up to their feelings for each other.
I don't remember the name of the story but that is the basis of what I remember from it.
Please help me find this story!
