Writer Casey Johnson and director Ken Olin spoke to PEOPLE about the latest episode of the show, titled "I've Got This," and shared how Moore's pregnancy and a storyline on the NBC series nearly mirrored one another. In the tenth episode of the current season, audiences saw Kate (Chrissy Metz) and Kevin (Justin Hartley) caring for their newborn babies with their partners Toby (Chris Sullivan) and Madison (Caitlin Thompson), as well as handling the new challenges of bathing a baby, sleep training and juggling parenting duties. "It was interesting because we filmed this right before Mandy left to go have her baby. It was neat thinking about her having a newborn and that in a couple of weeks, she would have her own newborn for the first time," Johnson told PEOPLE.

"I don't know how much it actually delayed the story, the writers all seem determined to tell these stories even though it's very challenging because there are so many restrictions on dealing with babies," he said about the young actors who play the Pearson babies in the present-day timelines. "And then dealing with Mandy's pregnancy, how we were going to accommodate her and make sure that she was safe," Olin added about another concern they had. "We actually started shooting this episode, I think, in December so that we could accommodate Mandy's pregnancy before she got too big. Then we finished a week, 10 days ago."
