Apprentice Part 2
Blackmailed into becoming Slade’s apprentice, Robin becomes an enemy of the Titans, to their surprise. When faced with the opportunity to blast Starfire, Robin freezes, causing Slade to activate the probes. Catching on to the ruse, the Titans find Robin at Slade’s headquarters. When Slade reactivates the probes, Robin touches the machine controlling the probes and becomes infected with them. Slade destroys the device and a battle ensues between him and the Titans, after which Slade is defeated. The Titans and Slade escape just as the building self-destructs. With the probe machine, Cyborg removes all the probes from the Titans.
