One of the funniest subplots of 5Ds is Jack constantly failing at absolutely everything that isn’t cardgames and/or motorcycles, and the rest of the cast going “Look, he may be a useless twink, but he’s our useless twink.”
Jack throwing all the spoilers at Paradox. There’s a very nice throwback all the way from episode 2 of 5D’s here. Jack saying you can’t win just with monsters is exactly the advice he gave to Yusei back then.
