"The Hub" is the ninth episode in the fourth season of the re-imagined Battlestar Galactica TV series. It first aired on television in the United States on June 6, 2008. The survivor count shown in the title sequence is 39,673. Plot A cold open reviews some of the events of the previous episode, Sine Qua Non. Text reading "Two Days Ago" picks up the story of President Laura Roslin and the other human beings aboard the damaged Cylon basestar. As the Cylon hybrid is reconnected, it cries out "Jump!" The ship jumps to an empty part of space. During the jump, Roslin finds herself aboard a dark, empty Galactica. Priestess Elosha, who died in the Season 2 two-part episode, Home, appears. She and Roslin embrace. Roslin admits she feels at home aboard the Galactica. The jump ends, and Roslin's vision ends. During subsequent jumps the vision recurs.

Roslin attempts to calm the Hybrid again, speaking to it more humanely, and the Hybrid seems to calm down even further. The jumps continue, as do Roslin's visions during the jumps. Roslin and Elosha discuss death and dying. The periods between jumps become somewhat lengthy. During one such period, Capt. Karl "Helo" Agathon discusses the mission with the Leader of the Eights. He and the Eight conclude that only by using the Galactica's Viper ships—several of which were trapped aboard the basestar when it jumped away from the Colonial Fleet—can they
