After such a big battle, you'd think the show would be done. But it's back, in this season premiere of Senior vs. Junior. Senior is well-rooted for battle, but Junior plans on destroying his dad's business regardless; by building a rival shop just around the corner. Of course Mikey will be there along with an old friend Vinnie.
