Adam decided he needed to hitchhike around the country to shoot a 15-part documentary on, like, the emptiness of the human experience or something. He didn't invite Jessa to come with him, and she knew it was over between them. (Thank god, because that relationship was the actual worst.)
Instead of having another downward spiral, Jessa channeled her energy into something more positive. She and Laird teamed up to open an unlicensed holistic sex therapy/nude yoga/crystal healing business out of Laird's apartment. They raised his baby together when Caroline took off again and formed a modern family.
Hannah and Jessa realized they're probably the only two people on earth who understand each other, and their friendship slowly pieced back together. Jessa continued to be the only woman in the history of ever who could pull off a furry bikini top as a shirt, and she does so well into her 30s.
