In this episode, Kanan tries to teach Ezra the ways of the Force, but it quickly becomes clear that not only is Kanan not a very good teacher, but he may not have been all that good of a student, either.  After all, as Yoda said, "there is no 'try.'"

Losing his temper and almost getting Ezra killed during a particularly complicated excercise, Kanan decides to attempt to break a legendary Jedi Master out of an impregnable Imperial fortress in order to foist the lad off on "the best teacher possible."
