While they taunt him, Janja speaks with Scar in the volcano, asking what to do next. Scar orders Janja to interrogate Zazu, who will have all the information on Simba, including his strengths, his weaknesses and his allies. Janja is confident that he can get Zazu to talk, and leaves the volcano to proceed with the plan.
