Way back in 2012, the first episode of Girls showed Lena Dunham’s character Hannah demanding financial support from her parents to help her become a successful writer in New York City. “I don’t want to freak you out, but I think that I may be the voice of my generation – or at least, a voice of a generation,” she informed them, before sliding off her chair in a magic mushroom-induced stupor.

Fast-forward to the final episode of Dunham’s groundbreaking HBO series, which aired on Sunday, and Hannah’s life is looking very different. Now a single mother living in a small town in upstate New York, she’s adjusting to a vision of her thirties that looks very different to what she might have imagined at 23 – although she’s still accompanied by her longtime friend, Marnie (Allison Williams). The episode ends with the screen fading to black after a shot of Hannah staring straight ahead, breastfeeding her new baby.

Hannah’s child, a son named Grover, was the result of a holiday fling with laidback surf instructor Paul-Louis (played by British Star Wars actor Riz Ahmed). In a new interview, Dunham reveals the story behind Hannah’s unusual choice of baby name.

“I came in one day and I was like, ‘The baby's name is Grover.’ And we were like, ‘Sounds about right,’” Dunham tells The Hollywood Reporter.
