The therapist Dr. Wheeler is clearly a supervillain in disguise, though I'm not sure which one. (Spellbinder? Not sure if that would be too soon since he just appeared)
I remembered seeing Ian Peek drift through bedrock and towards the Earth's core, but I must have misremembered since that didn't happen in the episode itself.
I thought that Zeta would find out about Terry's identity when Zeta was disguised as Max, or that Terry would cause trouble for himself by trying to stop shady government workers, though neither of those happened.
This disc has:
-Eyewitness
-Final Cut
-The Last Resort
-Armory
-Sneak Peek
-The Eggbaby
-Zeta
Not familiar with these, though I assume Zeta is a test-run for the DCAU's original show The Zeta Project.
