At last, Molly gets her well-deserved happily ever after! She's seen celebrating her 32nd birthday at the start of the series finale, surrounded by close friends and family. She later helps throw Issa a surprise birthday party at Crenshawn's office space and turns it into a fundraiser for The Blocc.
While visiting Tiffany and Derek at their new home in Denver, Molly gets a call from her brother Curtis where she finds out her mom died. The finale later jumps to her 33rd birthday, and over the phone, she tells Issa how hard her mom's death has hit her, saying, "I keep trying to wrap my mind around the fact that I'm going to keep having birthdays without her." But Taurean gives her the perfect distraction from her grief — the two get engaged.
We later see the couple at their wedding with all their friends and family, and there's even a sweet memorial set aside for Molly's mom. After the ceremony and reception, Issa helps Molly out of her wedding dress as the new bride expresses her newfound happiness. In the final scene, Molly wishes Issa happy birthday while she's on her honeymoon with Taurean, where she later jokes about how he "broke my pussy" — an ode to Insecure's series premiere.
