The Facility (1) - S1.E6

Yusei is arrested and sent to a detention center, where he meets an old man named Yanagi, who duels using what he calls his "Hidden Treasure" deck. Yanagi faces off against another prisoner, Bolt Tanner - and is shortly revealed to be a very poor duelist. Although lacking skills, he still cares deeply about his cards, something Yusei can relate to. Meanwhile, Goodwin reviews Jack's duel with Yusei, and discovers that, had they not been interrupted by the appearance of the Crimson Dragon, Jack would have been defeated.
