The Ninja finally put an end in the Serpentine situation, but that doesn't mean their troubles came to an end. Without Wu and having to train Lloyd all alone, they still have to deal with the remaining Serpentine, Lord Garmadon in possession of the Golden Weapons, a group of thugs with some fixation on sea creatures, evil versions of themselves, pirates... What else can appear?
And even with all that, maybe the real challenge is the reality of being a normal teenager living a normal life. With new friends and new foes, the Ninja still have a lot to learn about life and themselves.
