 Kathryn Alexandre appeared for the first time in this episode as Alexis, a Prolethean midwife. After working as a script reader during Orphan Black's initial auditions, Alexandre began working as Maslany's "clone double": playing opposite Maslany in any scene when multiple clones interact and being replaced with Maslany in post-production. Fawcett and Manson had planned to cast Alexandre in her own role from the start of the show's second season, and had considered casting her as Gracie before deciding that, due to the amount of interaction between Gracie and Helena (played by Maslany), it would "turn into a mess if we cast her". They decided to find a smaller role for Alexandre and eventually settled on the part of Alexis.
