Episode 7 reveals deeper layers of Axel and Chris' darkest secrets, adding complexity to their characters. It also uncovers that Dr. Skinner was a former associate of Hersch, which introduces new dynamics of suspicion and distrust within the Lazarus team.

The episode uncovers that Dr. Skinner purposely guides the team to live out experiences that led him to create Hapna, a drug inspired by a condition called 'analgesia' that causes numbness to pain. Skinner's plan appears to be more complex, possibly positioning him as an anti-hero acting in humanity's best interest. Additionally, Skinner had bought land on islands that are now submerged due to global warming, which the team investigates.

The episode highlights the environmental disaster of melting polar ice caps and flooding of coastal areas, which Dr. Skinner predicted. It shows the world losing the last icecap at the North Pole and several islands submerged by rising water levels. The episode also includes commentary on human destruction of the environment as a cause of apocalyptic events, linking to the Biblical Book of Revelation.

The Lazarus team retrieves the memory bank of the AI Naga, which was modeled after Skinner's brain but created without his involvement. The memory bank provides data pointing to four submerged locations connected to Skinner, which the team explores to find him and understand his motives.

Episode 7 is noted for being slower and more atmospheric, focusing on mood and detailed imagery rather than fast-paced plot. Most of the episode builds world and character atmosphere, with significant plot revelations occurring mainly in the final minutes. The scuba-diving scenes and exploration of submerged islands contribute to this mood-driven storytelling approach.
