I've been thinking about how the writers can accommodate CCA's pregnancy into the season 10 opener. Usually they end a season with a cliffhanger, which continues directly into the opener of the next series. I don't feel that the end of season 9 was a cliffhanger, so they could easily begin 10 with a 'six months later' episode, showing Monica being pregnant. It's well known that when many couples stop trying to have a baby and decide to go down the adoption route, they become pregnant. This could happen with C and M.
The other three couples could also be well established by then. These are, after all, people in their thirties - it's time they started settling down.
Any views, anyone?
