The Riddler seemingly gives up crime but Batman still has his doubts.
- Berserk Button: Being called crazy is this for The Riddler.
- Bombproof Appliance: Batman hid in a safe. Even the Riddler couldn't figure this stunt out and was nearly driven insane by it.
- Chronic Villainy: The Riddler sells his persona for a fortune and decides to abandon crime altogether in order to avoid risking his newfound wealth and freedom. However, because he has such a compulsion, he reasons that the only way he can do so is to kill Batman. Naturally, he fails, gets found out and arrested.
- Cut Lex Luthor a Check: Riddler has sold the license to his persona to a toy developer for a completely legal fortune. However, Batman is convinced that he will continue to commit riddle-crimes, even though it will jeopardize his freedom and financial well-being. When Robin wonders why he would take such a risk, Batman explains that for him it is not about the money, it is an obsession. As it turns out, Batman's right; Riddler is uneasy with his new life, and eventually decides to try to kill Batman once and for all just to remove the temptation to backslide.
- Cutting the Knot: Batman is locked in a showroom while a bomb goes off in 10 seconds. Riddler is stumped as to how he survived. Simple, he hid in a nearby reinforced safe.
- Go Mad from the Revelation: Inverted when Batman survives the Riddler's death-trap, but will not tell him how he did it. The episode ends with Riddler ranting and raving as he tries to figure out how it was done.
- Riddle for the Ages: Played with. When Batman is able to escape The Riddler's deathtrap of sealing him in a building that has high explosives in it, the Riddler is so bewildered by Batman's escape that he no longer cares about going to Arkham or losing his now legitimate business and lifestyle and only cares about finding out how Batman was able to survive a trap he clearly shouldn't have been able to. While Bruce later explains it to Dick Grayson, and the audience, back at Wayne Manor, he never explains it to the Riddler himself. Mr. Nygma ends up going even more insane due to not getting an explanation.
- Villainous Breakdown: Riddler has one just because Batman will not tell him how he survived a seemingly perfect deathtrap.
