In All the Little People, Finn mentions some C-listers and says "don't worry, they'll get involved eventually".
It just so happens that two of the people he specifically mentioned (Xergiok and Tiffany) got involved in the show. Anyone else think that was foreshadowing the idea that old, small characters are going to get involved in the show?
What about when Party God was in Party's Over?
Or how about the squirrel that shot an arrow at Jake?
I dunno, just a theory.
