S01E90: The Race to Escape (2)

As Kalin escapes with the kids and their father, Sergio, the pursuers start activating the father's shock collar, but Kalin manages to stop it though nearly falls off the kart in the process. Yusei manages to avoid losing to effects, but Lawton instead summons a more powerful monster. Kalin's group are directed towards a deadly gap, so West and Nico's father jumps to change the tracks to safety, and Sergio falls into the abyss in the process (and dies). Yusei manages to summon Drill Warrior from his graveyard, and Kalin knocks into Lawton before he can respond to it. Lawton then throws some dynamite which sends everyone flying, with Yusei and Kalin falling into a canyon. Lawton kidnaps Nico and West, and along with Barbara overthrows Malcolm. As Yusei and Kalin visit the father's (Sergio) grave, his duel disk reacts to Kalin, who decides to fight with Yusei.
