We've got a brief synopsis of what we can expect for the two part season premier. It's not too spoilery, but just in case you are freaky about any spoilers I'll put it behind the break. Although I will say this, it looks like we're getting a new villain, and I'm calling it now, the villain is Zecora, think about it.
