In the episode King Worm s4e09, when Lich comes out of Finn's belly, his (Lich's) clothing is similar to the Farmland Finn, could it be possible that Finn is somehow connected with him? "Billy" talked about multiple universes, what if the Lich is actually Finn from another universe wanting to destroy the one where "our" Finn lives?
