What is the first episode in season 5?

Alright, it says on wiki that it's going to be called, "Finn the Human" and the one after that is called, "Jake the Dog". But anyway Finn the Human is going to be about how Finn and Jake chase the Lich through a dimensional portal where they meet the Wishmaster, who tells them that the Lich wished for destruction of all life. This leads Finn to wish that the Lich "never even ever existed". It will air on Nov. 12th and "Jake the Dog" will also air the same night but it didn't say what the Jake episode was about. Hope this helps!
