These characters are Caleb Dume and Master Depa Billaba, Caleb would go to take the name of Kanan Jarrus when he had escaped the Empire after the great purge. "Star Wars: The Bad Batch," as well as the 12-issue comic series "Star Wars: Kanan," show the challenges of his escape, but in "Practice Makes Perfect," we get to see a much more idyllic time for the young Jedi.
