In a registry office, a woman agrees to marry the children's father after the kids plead for a mother. They pose for photos while people wait; the registrar asks for vows and documents. The woman balks, then accepts a one-year arrangement: she will live as their mom for a year and may leave afterward. The father asks if she intends to be a permanent stepmother; she refuses. At episode end she confronts him with a direct question—who is the children's biological mother?—leaving the new marriage and motives unresolved.
