Oh No, I Didn't

Oh No, I Didn't is the sixteenth episode of Tenkai Knights. It first aired on December 7, 2013 on Cartoon Network in the United States.

Plot
At school, Guren thinks about what Gen, Beni, and Dromus have been saying to him. When Ceylan tries to cheer him up, Guren absent-mindedly asks him if he's ever wondered why they were chosen to be the new Tenkai Knights.

Guren's question leads Ceylan to wonder what skills he brings to the team and he starts suffering from self-doubt.

The next day, Ceylan goes to Mr. Whites shop to ask Mr. White himself why he and the other boys were specifically chosen to be the Tenkai Knights. When he doesn't get a satisfactory answer, he sneaks off to Quarton. There, he, as Tributon, asks Beag what he brings to the team. Beag misinterprets the question and the pair and the soldiers are attacked by Slyger and Granox. When Tributon attempts to fight the pair alone, he is overwhelmed by their new Titan Mode transformations.

After this, Ceylan is convinced that the other boys would be better off without him and quits the team. When they are summoned to Quarton, Ceylan at first refuses to go, but upon seeing a vision of the others in danger,  he rushes off to help. When he arrived, he helped the others defeat Slyger and Granox. When they returned to Earth, Ceylan's confidence is restored.

Trivia
