In the last episode of Brothers & Sisters, Kitty wanted to have a low-key baby shower, without any party games or extravagant gifts, but things didn't exactly go that way, thanks to Nora and Sarah. There were some funny moments, too, courtesy of the gay men who were not so surprisingly invited to the shower.
Also, she got an offer from her alma mater to start up a new university department on broadcast journalism, which is only her dream job, but she considered that the baby might be a factor soon. Of course, Robert wanted her to take the job (because he was a little guilty that she should make the sacrifices he wasn't willing to make), but Sarah sort of implied that babies tend to be huge work. Finally, she decided that the baby was definitely more important than her career. This was the central dilemma in the last episode, the classic career versus family variety. The moment Kitty finally decided to have a baby, her dream job came knocking.
