In "Surro-Gate", Greg and Terry find a surrogate in Francine against Stan's wishes. Greg is scared of being a father but loves his new child instantly when he sees her. After the baby is born Stan's kidnaps her because he is against gay parents and names her Liberty-Belle.

It is revealed in "Anchorfran" that Terry left Greg to follow 311 on tour, leaving Greg heartbroken over losing his news partner. Francine fills in, but soon takes over the show until Memphis Stormfront, the new weatherman arrives and proves to be better at exchanging banter with Greg, resulting in Francine demanding he be fired and Greg quitting to open a bakery. To get Greg and Memphis back, Stan calls CIA Weather Control to arrange for a monster storm which works, although when they insist Greg and Memphis kiss hoping to spark a romance, Memphis reveals he is straight.
