Maybe this is Finn's Father, immediatly after the mushroom war, but right before magic fully emerged. And the ending scene had nothing to do with Fin in an alternate universe, but the beginning of an explanation to the Lich king and the mushroom and Marceline's past and Susan strong and all the other unfinished backstories! And towards the end of season five all the knowledge gathered will be put into use as Finn and the others battle the Lich king for the final time. Hey, one can only hope.
