Need to catch up on The Walking Dead before the midseason finale this Sunday? AMC has just the thing with a Walking Dead season 3 marathon.

Leading up to the winter finale of The Walking Dead on Sunday, you can watch all seven previous episodes that have aired so far this fall in season 3. Starting at 2/1c, be sure to give yourself a refresher course on this season’s action, or catch up on any you may have missed.

After season 2 left us wanting more – with the group on the run and the introduction of the mysterious Michonne, a lot has happened so far in season 3. We’ve been introduced to Woodbury and the Governor, and if everything there seems too good to be true, well, it is.

Rick and his crew discovered a prison and focused on settling in there, but as you could imagine, creating a home in a zombie apocalypse isn’t exactly easy.

With the conflict between the prison and Woodbury creeping closer and closer, will we finally see the two collide on Sunday? We might even see some new faces introduced in the season 3 winter finale, some of whom could turn out to be major characters.

Tune in on Sunday to AMC starting at 2 p.m. EST to check out The Walking Dead season 3 marathon, and catch the midseason finale, “Made to Suffer,” at 9 p.m. EST.
