Star Wars Rebels Episode 13 Call to Action Episode Title:Call to Action.Episode Description:In light of discovering that Trayvis is actually an Imperial spy, the rebels debate broadcasting a message to the nearby star systems about their cause. Ezra adamantly supports the idea, since his parents had broadcast secret messages from their basement for years. Kanan decides to invade the main Imperial communications tower on Lothal. They think they have the element of surprise, but they do not take into account the arrival of Grand Moff Tarkin, who has deduced where they will strike. The Inquisitor and Kallus are sent out to capture Kanan alive to earn back Tarkin's trust. When the Imperial forces attack the group at the tower, Kanan instructs the team to leave him and thus is captured. The team is able to send a message of hope, urging those living under the oppression of the Empire to fight, before Tarkin orders the tower to be destroyed, ending their broadcast.
