Rhys knew nothing of Torchwood and believed that Gwen worked in "Special Ops" and that any alleged alien interference with Earth over the past two years were actually mass hallucinations induced by terrorists putting psychotropic drugs in the water supply. When Gwen put this theory to Jack he derided Rhys as stupid. (TW: Everything Changes).
