Ep. 22: Electra confronts Nemo over Tartessos while the Nautilus sacrifices itself to destroy the Garfish fleet.

The Nautilus detaches its combat block to self-destruct with the Garfish fleet, saving the ship. Nemo moves the children to his cabin, warning they will be jettisoned. Electra shoots Nemo at gunpoint, revealing her tragic past. Thirteen years ago in Tartessos, Nemo stopped Gargoyle from using the Tower of Babel, destroying the kingdom and killing Electra’s family. Nemo rescued Electra two nights later, and she fell in love with him. She learned Nemo caused Tartessos’s fall but remained loyal to his goal against Neo-Atlantis. Jealous of Nadia, Electra tries to shoot Nemo again. Nadia realizes Nemo is her father and regrets her behavior. Nemo explains he fights to atone and spare Electra suffering. He stops Electra from suicide, releases the children, and urges Nadia to live.
