Desi turns out to have been concealing an oxycontin addiction. Jessa (Jemima Kirke) and Adam (Adam Driver) are having trouble in their wild relationship and decide to make a film of Adam and Hannah's strange relationship.
In one of the most interesting episodes of the season and the series, Hannah has a strange interview with Chuck Palmer (Matthew Rhys), a popular other accused of taking advantage of young female fans with his fame. The interview grows especially intense when he makes a move on Hannah and his daughter arrives. Ray (Alex Karpovsky) is troubled about his stagnant life when the owner of the coffee shop where he works Hermie (Colin Quinn) passes away leaving him the place. Hannah goes to the hospital for a UTI infection where she encounters Joshua (Patrick Wilson) the rich doctor she'd once had a short tryst with and he tells her that she's pregnant.
Hannah decides to keep the baby causing strange behavior from each of her friends. Elijah (Andrew Rannells) goes on an addition for the play version of "White Men Can't Jump" and is upset with Hannah's change in lifestyle. He wants to continue to party and be immature while Hannah will be forced to grow up. Hannah's mother Loreen (Becky Ann Baker) struggles with a new phase of her life after her husband came out as gay and divorced her. She is upset to find out that she is a grandmother and life has passed her by with a man who didn't love her.
Shoshanna (Zosia Mamet) has her own troubles with old friends who became successful clothing moguls and rushes into a marriage with a man she meets only two weeks before. She introduces Ray to an old coworker who hit it off quite a lot. Adam tries to win Hannah back and help her raise the baby and after a day of discussing the reality of the situation, they find that they do not have a future together and silently and emotionally break up.
The girls of the show finally have one cathartic meeting in a bathroom where they all agree that they are moving in different directions, though Marnie is determined to stay friends with Hannah. The final episode flashes forward three months to Hannah and Marnie living with Hannah's young child who refuses to breastfeed. The trouble of motherhood brings Hannah's own mother to their country house. Hannah finally shows maturity and seems to be really changing of six seasons of odd and seemingly immature decisions. Girls has been a fun little 30-minute comedy after HBO dramas that was always interesting to watch as Lena Dunham explored the life of a woman in New York..
