>>96822526Regarding SU the answer is easy
SVTFOE doesn't quagmire itself with pointless side episodes that bring it's plot to a grinding halt just for the sake of being quirky. Also while there's certainly a lot of shipping in both Svtfoe doesn't have runaway scripts written just because one person wants to see his/her ship succeed.
Gravity Falls I actually think handled itself pretty competently for having only 2 season to wrap itself up. SU will continue to slog on until it's cancellation or the CN executives force Sugar to end the show at gunpoint
