Matryoshka
Nadia and Alan argue in the bathroom over what to do. She wants to keep the younger version of herself. He insists that she needs to return her younger self. She opens the door and sees the birthday party. She closes it and reopens it and sees a classroom of Jewish boys.
Nadia, Alan, and the baby (which he is now holding) wander through the classroom and make it back to the party where they continue to debate. Nadia is steadfast until Ruth shows up. Everything seems kind of normal until Alan notices that there are multiple Ruths. Nadia gives in and agrees that they need to return the baby, in order to set things right again.
