Ilana embarks upon her latest moneymaking opportunity when she opens an outdoor workspace for New York City smokers; Abbi stands up to her landlord after he refuses to update her plumbing.

Ilana visits an old flame to cash out her share of Bitcoin; Abbi drops off her laundry for the first time and loses her favorite sweatshirt.

Ilana discovers a terrifying secret about Jaimé; Abbi tries to make the jump from sweater-folder to window artist at Anthropologie.

Abbi gets invited to a fancy art event at MoMa; Ilana and Lincoln have their one year relationship check-in.

The girls meet Ilana’s 16th cousin – who is a Holocaust survivor – and take him to a drag brunch; Abbi tries out a new look.

Ilana gets recruited to be a hair model; Abbi’s new flame tells her that she’s not mature enough.

Abbi and Ilana visit "Sleep No More," and Abbi tries to find the right time to tell Ilana some life-changing news.

The broads say goodbye.
