Jessa Johansson

(Jemima Kirke)

Rehab did wonders for Jessa, who has been able to hold a job and even begun a real, semi-healthy relationship — with Hannah’s ex, Adam. It’s her recovery that brought them together after their chemistry sparked in an AA meeting. In the season 5 finale, they had a violent fight in which Jessa confessed that she’ll never forgive Adam for breaking up her friendship with Hannah, but the couple managed to make up before the end of the episode.
