I honestly think in ‘Five Short Tables’ when Marshall is shown as Gumball’s regrets, I believe it meant Gumball regretted ruining the relationship between him and Marshall, as Marshall seemed really hurt in the flashback.
Adventure Times’s Five Short Tables was so gay. *heavy breathing* gUMBALL REGRETS BREAKING UP WITH MARSHALL LEE, WHEN TURTLE PRINCE AND FLAME PRINCE WERE TALKING THEY WERE ALWAYS BLUSHING aND AND IT WAS SO HOMOROMANTIC?!???!!!!! I ACTUALLY CAN’T???!!???!
