"The Lich" Storyboards

    A lot of information was cut out of the season 4 finale of Adventure Time.  First of all, the Lich is inside Billy from the dream on.  Second, when Lich/Billy says "I'm going to push the Lich in there" he isn't referring to just the void he is referring to a prison dimension.  That's not all either, Finn's dad was a great hero of Ooo that was unjustly locked up in the Prison Dimension.  The Lich also says to Finn when he is bargaining for the book that he can bring his parents back.  I assume that any similarities to Harry Potter are purely coincidental.
