'Knight After Knight' is a good episode. In it, we get a monster who steal people's courage. He did it to Fury first. Then, he did it to the 4 main male rangers. Ivan thought that they weren't worthy, because they lose their courage. So Ivan went in search of those that he believed were worthy. The guys he found prove themselves not worthy when they ran from the monster. After a speech from Keeper, they managed to get their courage back. It allowed them with help from Shelby and Ivan, to finally defeat the monster.
