Vostok was raised in a solitary chamber outside of the Baikonur Cosmodrome, taught to thrive on isolation so that he would become the ideal cosmonaut for the Russians. In Siberia, Arthur Curry was so set on catching Black Manta that he had no intention of saving the villagers. Vostok-X was unsure about leaving them to die because, like him, they were Russian. The Others, despite Aquaman's wishes, returned to the village and saved it.
