Jack thinks Seto has taken Yusei and Crow hostage, keeping them in the Kaiba Corporation building. The only way to get to them however is through Seto. Seto thinks Jack has taken Mokuba(this is his what, like 9 millionth kidnapping?) and will confront Jack to get Mokuba back. The loser not being able to accept defeat and losing their loved one(s) soon turn it into an all out brawl. Who wins? Why?
