Finn the human

Being the last human on Ooo was a key trait for him, literally being called 'Finn the Human'. Finn always felt like a novelty, like an artifact of the old world, an embodiment of the world before the Great Mushroom War, a last remnant of humanity. And yet, being human was his most vulnerable and isolating trait at the same time. Because he knew he couldn't find anyone else like him, no one he could truly feel a kinship with in that sense, as he knew few people who shared the reality of mortality. At least until he met you. Another human in the midst of the complete opposite. Someone equally susceptible to death, someone else who would have been thought of as 'ordinary', if the norm had been for humans to be a common species, as they had been before the War.
