I've only played the Fyres once. Moira and Dominic are very much a loving couple in my save, always hugging and seeking eachother out. They had another baby when Morgan was still a teen, of course another girl :D
Dominic is still climbing the career ladder, but can't really decide between comedy and music. I believe music suits him better. I mean, he has to grow up SOME time, can't hang with the cool kids, dancing and DJ'ing the nights away forever. I figured with the huge property they have, I'll build a large greenhouse. Moira is working from home there as a gardener, which I think is perfect for her.
The house has been changed a bit, to fit the family better. At least in my opinion, premade houses can have some weird floorplan with some very inefficient flow to it. If you've ever played the Bailey-Moon house, you'd know what I mean :# That house is horrible.
Anyway, last I played them the baby had become a toddler, and both the older girls had moved out.
