Gabe makes an elemental discovery. Tanya and Sasha play cat-and-mouse. Gabe's efforts to learn about his supernatural hitchhiker finally pay off . . . but a little knowledge can be a dangerous thing. Sasha makes a surprising discovery when investigating Tanya's radio. Rumors of golem sightings have left Prague on edge. And when Jordan and Alestair send Gabe to Tanya for assistance in ridding himself of his unwanted guest, the two rival spies hatch a desperate plan to help each other get what they want: for Gabe, freedom from the hitchhiker; for Tanya, her stolen radio. But as the Rolling Stones put it, "You can't always get what you want." This episode is brought you by Ian Tregellis, who you should think twice about ever double-crossing.
