Oh.
JOUNOUCHI: You're like some deadbeat, with your boots kicked up on the table like that.
More literally, "Looking at the soles of your steel-toe boots reminds me of a real low-life".
Ohhhhh.
Who else!! Would that be!!!
Now, idk if Takahashi-sensei meant for that to be a call back. Jounouchi's alcoholic father hasn't shown up (and never will again) since the first volume of the manga. The series underwent a hard reset, after all, to shift towards the card game.
But this panel is always at the back of my mind. When Jounouchi was a contestant at that rigged gameshow, his hope was to restart his relationship with his father if he wins the prize money (to pay off his father's gambling debts).
Jounouchi is such a good lad.
