We are alll aware that some people believe Fionna is Finn's mother. But, looking at the evidence, this is most likely true. If you watch Beutopia, on one of the skulls lies Fionna's hat. Is it possible that Fionna died at this river? Did she know Susan? Is she Susan? Another thing, who's the father? We have to wait for season 5 or so to find out.
