>>90085044>but it would be terrible in canon.
Perhaps in present terms, but there is history to fall back on.
Initially, Finn and Marceline had more onscreen chemistry than other characters in the show...but that kind of went the way of the dodo when the relationship drama began around Season 3, with Marceline only became an accessory to PB stories and vice versa.
The two had such great potential, it's sad to see it go to waste as it did. I still ship them but it is hard to see it happening with the direction the show has taken in the past five years.
