I saw it!!!!! Doug was going to devorce Carrie for keeping the apartment. Author's wifey person decided not to marry him because she thought he was gay, so he married spence's mom. The adoption place called and gave them a picture of a baby they could have. Carrie and Doug were going to get 'devorced' and they both wanted the baby so they raced to the airport, each trying to get the baby first. BUT!! On the plane they made up and got back togeather, and Carrie was pregnant!! So in the end they had two babies, Author came back in the end also, saying his marriage didn't 'work out'.
=P
