2x16 - Space Battleship Yamato

The Star Force prepares to leave Telezart. Mark Venture tries to stay behind. To get him back to the Argo, Treleina agrees to come with the Star Force. But, once Mark is safe onboard, Treleina jumps ship, literally floating back down to Telezart. She leaves a message for Mark explaining her deception and confessing her love for him. She agrees to stand up to the Comet Empire, and stands at Telezart's surface as the Argo pulls away.
