Plot: With the 3rd gear stopped, the Signers gain access to the Center Gear, and Yusei rejoins the others, telling them the truth about Antinomy, and about the Delta Accel Synchro method. They continue onwards to the center of the Ark Cradle, where they spot more, but smaller gears, as well as the Ener-D Generator that was called the Center Gear, which was powering most of the negative Ener-D of the Ark Cradle
