Nightwing, Artemis and Black Lightning return to Bedlam to retrieve the captured metahumans and Superboy, learning that the princes' uncle, Frederick DeLamb, is mastermind Baron Bedlam. Although the team is able to rescue Superboy and Prince Brion, Count Vertigo gets away with the other kidnapped victims. Brion awakens, and is revealed to be able to control geologic forces. He goes to the castle to confront his uncle, who has since framed him for Markovian metahuman trafficking. Plasmus, the Count, and Simon Ecks engage the heroes in battle while Superboy goes to help Brion. Prince Gregor realizes that DeLamb is responsible and has him arrested, but exiles Brion.
- Barrier Warrior: The rescued Quraci refugee is able to create shields and bubbles to protect herself and the heroes, leading Artemis to call her Halo-girl.
- Call-Back: Artemis comments that Superboy is not not going to like being unconscious in a pod, which is a reference to the pod Superboy was in at Cadmus in Season one, episodes 1.
- Colour-Coded for Your Convenience: Halo's different powers produce different colored fields: force fields are red, flying/levitation is orange, and resurrection is violet.
- The Cameo: Courtney Moore is the reporter who interviews Garfield in the beginning.
- Doppelgänger Spin: Simon Ecks's Self-Duplication clones confuse the heroes, but are easily taken down.
- Gratuitous Laboratory Flasks: After everyone leaves the secret underground lab, a green liquid bubbles out of a test tube catching on fire from the flame of a bunsen burner.
- Labcoat of Science and Medicine: Exploited; to infiltrate the children's hospital Nightwing takes a labcoat from a rack and puts it on.
- Offscreen Romance: Apparently, Beast Boy and Queen Perdita began dating during the Time Skip after Season 2.
- Portmanteau Couple Name: "Gardita" for Garfield Logan and Queen Perdita.
- Pyrrhic Victory: The heroes shut down and expose Bedlam with its mastermind, Baron Frederick DeLamb arrested, and they save Prince Brion, Dr. Jace and Halo; however, Brion is exiled by his brother to minimise the fallout (and for his protection), Vertigo escapes with all the other kidnapped victims, and Plasmus is freed from their control only to be shot dead by a terrified farmer. While Dick tries to encourage focusing on the positives, it's clear nobody is exactly happy with the final outcome of the mission.
- Race Lift: The original Halo character was created when an energy being, an Aurakle, reanimated the body of a murdered blonde white woman. In this version, a Quraci refugee with a middle eastern appearance wearing a hijab is reanimated.
- Significant Anagram: Lampshaded; "DeLamb" is an anagram for "Bedlam". Nightwing kicks himself for not having noticed that.
