Next episode: Tatsuya and Yuuri are together again, cloaked in blankets and drinking hot drinks, while Tatsuya teases her. And Gien is controlling a gigantic, golden robot. The group has boarded the Time Ship. Tatsuya's voice, "The 30th Century might be destroyed if they stay here, so I need to get them back." I think he has tricked the others into boarding the Time Ship, and locked them in to get them out of here. He hollers into his Chrono-Changer. They stare out the window, horrified. Yuuri screams his name, while the others hold her. The V-Rex fights Gien's latest creation. And Naoto, blood all over his face, stands in flames and wreckage with his gun in a shaking hand, eyes wild.
