In the bathroom, Cakara spends a lot of time contemplating.
He thought carefully about the attack strategy he had proposed to Uncle Yoda during the emergency meeting earlier. As someone who understands the ins and outs of North Amerta, Cakara has a glimmer of hope. He was sure that if his predictions were correct, they would still have time to save the captives, even though… the Guardians must have tortured them so severely.
He regretted the plan of torture he had made with his sister. His sister was in charge of creating the torture serum while he designed the stages of the suffering. He remembered that this was the most torturous moment for him. He never intended to do that, but his father's threat involving his mother he couldn't ignore. For the sake of his mother's safety, Cakara obeyed his father's orders and created an extraordinary plan of torture.
Since then, he has hated his father in silence.
