The crusade of Rittenhouse was unveiled by its philosopher, Nicholas Keynes, on Timeless Season 2 Episode 2. And it's not a pretty concept.
Surely historian Lucy would recognize the striving for a master race when she sees it. You would think her historian mother Carolyn would also. But I guess you overlook things such as mass murder when it benefits you.
That final scene, in which Keynes laid out his vision of Rittenhouse, had a real "Triumph of the Will' feel to it. Even Carolyn looked a little uneasy, and she set the whole thing in motion.
A scrappy sextet versus all the agents of Rittenhouse hidden among the powerful through U.S. history really doesn't seem like a fair fight, does it?
