Morgan and Grace eventually decide to raise baby Mo as their own, even though Grace “has, at that point in the story, really not processed the loss that she had last season,” co-showrunner Andrew Chambliss told Decider last October. (In case you missed that heartbreaking Season 6 moment, Grace’s baby, Athena, was stillborn because of radiation exposure from a nuclear meltdown.)

In the Season 7 episode “Six Hours,” however, Grace turns a new page with baby Mo, as co-showrunner Ian Goldberg explained. “One of the crucial aspects of this episode and what it was about emotionally is Grace at the beginning, feeling so isolated and disconnected from this child that she wouldn’t even sing to the baby,” Ian said.

Ian went on: “And we knew that by the end of the episode, based on the journey that she went on, that she would sing to the baby, and that would be the symbol of acceptance and connection with this baby. … So the baby was always going to survive because we did want it to end in a place of hope and actually bringing the family unit of Morgan, Grace and the baby closer together even amidst a world that is pretty dire.”
