The Architect

S1, E5: Taking some time away from Providence, Rex encounters an enclave of brilliant engineers who are working under the direction of an enigmatic thinker called The Architect. Rex cherishes the chance to experience what a real family feels like, but can't help but feel something is amiss. Breaking the cardinal rule of the commune, he confronts the Architect and learns he is in fact a robot under the control of Zag R.S., an artificial intelligence determined to wipe out all nanites. To do so however, all of humanity will perish as well.
