Mind Over Matter

S1 E6: At an outdoor market run by the Moles, Hannah learns that Scharnhorst and Fesseden have accessed a high-tech cybernetics lab. When she tries to access the lab herself, she is captured by city guards; it takes Jack disguised as such a guard to liberate her. Fesseden activates the lab's dangerous tunneling robots, which seem to have minds of their own, and immediately make moves to break out of the compound. In the ensuing battle, Jack and Hannah elude Scharnhorst and, with the help of the Moles, bring the underground lab crashing down on the unstoppable machines.
