That night, the Abigail begins to unexpectedly malfunction, and Travis attempts to investigate the issue, which he discovers to be an undead clogging the water intake.
While he makes the necessary repairs, Nick, Alicia, Chris, and Daniel use the Abigail's launch boat to travel ashore to scavenge supplies from a plane crash.
The five of them escape on the launch boat, but Alex requests that they make a brief to stop to rescue another plane crash survivor, Jake, who is severely injured and located on a life raft nearby.
The site consensus reads: "A powerful crossover with sister web series Flight 462, 'Ouroboros' adds depth to the Walking Dead universe with enough fierce action and set changes to enliven the show's still-fuzzy perspective.
"[1] Matt Fowler of IGN gave "Ouroboros" a 7.5/10 rating stating: "'Ouroboros' benefitted greatly from some intense zombie action and the inclusion of the two main characters from the Flight 462 tie-in series.
