A Score to Settle (2)

Yusei defeats One-Hundred Eye Dragon, but is fully aware that it allows Kalin to draw his Earthbound Immortal to his hand. Back in the last days of the Enforcers, in a flash-back of Yusei's memories, Yusei, Jack and Crow try to talk sense into Kalin, and they all end up running away from Sector Security. One Sector Security officer pins down Kalin, but he manages to jump on his Duel Runner, causing him to crash with a bad head injury. He tries to finish him off but Yusei stops him. Yusei tries to pose as the leader of the Enforcers in order to protect Kalin, but the chief of Sector Security at that time had already figured it out that Kalin was the real leader of the enforcers, and Kalin becomes furious when he sees his hand on Yusei's shoulder, thinking Yusei had ratted him out. Kalin then gets harsh treatment in prison, losing his deck, and he was eventually convinced by the voice of Roman to become a Dark Signer.
