Living In Miserable Sin (S04E03)

Tom and Diana soon discover that cohabitation isn’t as idyllic as they had hoped. He finds her messy habits and quirky antics, like using a slingshot to feed squirrels, frustrating. Annoyed, she opts to leave and takes up residence with Sarah, where she attempts to be a nanny for baby Diana, though it’s not her strong suit. Meanwhile, Tom feels her absence keenly, particularly when Geoffrey chooses to move back in with him.
