Speaking of fresh babies, Jo reveals to Link that she's signed up to serve as a safe haven volunteer, picking up abandoned babies at firehouses and keeping them safe until they're picked up. She explains that she's taken on the role in an attempt to make nice with her past as an abandoned baby, but when she gets her first call to Station 19 (yes, it's a crossover episode) she runs into some trouble. She's immediately enamoured with the aforementioned newborn and by the end of the episode, she tells Link "it was too much, too soon," revealing she's taken the baby boy home with her.
