More likely either:

A. A new human female character who is Finn's age will be introduced

B. Something will happen that will bring Fionna into the real world (remember, the multiverse theory has been proven to be true in-universe; Fionna is somewhere in the multiverse)

C. Something happens that makes FP human (after it is reveleaed that Flame Lord had mind-controlled Finn and FP into breaking up)
