This series began again to complement the strong season events. The season opens with Matt and DJ who decide to destroy each other's work, and the dirty-iversary of Steve and DJ turns into a thrilling contest to present a wide range of gifts. On the other hand, Steph performs at her first children's concert.
The whole series has been all about family, but the first few episodes of Season 4 do a great job of making family bonds a very cohesive thread. It's like the Fullers, Tanners, and Gibblers are finally coming together as one big unit.
