Plot Synopsis

The Turtles and Serling are trying to figure out what's happening to Splinter now. April and Casey arrive and meet Serling. They also find out The Turtles were in the future and Splinter is gone. Casey knows the karate and goes to karate school where the teacher is Master Khan. It's revealed Master Khan is evil and hypnotizes his students, including Casey, to get rid of the Turtles. The Turtles save Casey and the others and everybody find out what happened to Splinter now.

  • April stated that the turtles were gone for a whole year, meaning that it is possible that everyone is a year older now, making the Turtles nineteen years of age and the events of the previous episode before the turtles and Serling went home was set in 2106. They turn twenty during the Back to the Sewer season.
