Here's something i forgot to mention - S4.E5

Molly invites Florence over for breakfast and a talk, but doesn't feel like doing much of either. Later, while browsing in the pregnancy and childbirth section of a bookstore, she's surprised to find Moss Goodman assembling a pregnancy book display and makes a date with him for dinner. That night, on their way to a police awards banquet, Molly breaks the news of her pregnancy to Hawthorne, who doesn't know quite how to react when he learns he may not be the father.
