Generator Rex Season 3 Episode 13 A Brief History of Time Episode Title:A Brief History of Time.Episode Description:Van Kleiss is revealed to have been sent back in time to the Old Kingdom of Egypt, where he created Gharun Set and the Sphinx, and engineered the technology in the Hall of Records as a means of returning himself to his own time. Van Kleiss is being pursued by a mysterious force, which he is convinced is an "antibody" of spacetime which is attempting to destroy him for being a violation of the laws of physics. Van Kleiss evades the force and places himself within what appears to be a time machine, awakening centuries later in the 2nd century AD, where he is captured by Roman soldiers. Van Kleiss is brought to the Colosseum in Rome, where he wins the favor of Emperor Septimus Severus, who worships him as a god. Van Kleiss is able to repair his machine and escapes once again as the entity pursues him, jumping across the eras in a desperate effort to make it home. In the present day, Rex tracks down Van Kleiss to Paris, learning that the device he built was not a time machine but a storage chamber which preserved only his nanites, meaning he was aware of every single second that passed. Rex frees Van Kleiss from the machine, and confronts the entity, revealed to have been Breach, who was pulled along with Van Kleiss during his trips through time due to the machine he attached to her. Rex destroys the machine and Breach vanishes, while Van Kleiss (who seems to have lost his mind from the experience) is captured by Providence.
