Jesse and Michelle juggle co-parenting their daughter, Isabella, while starting new relationships. Janet and Jason are adjusting to life with newborn son Cameron and Danny and Nia are overwhelmed with “three under 3.” Kristen and Luke are ready to keep trying to conceive their first child and Jasmine’s girlfriend, Melissa, has moved to Los Angeles. The group kicks off the season at Brittany’s White Party, but unresolved drama lingers between Kristen, Janet and Zack.
