After taking Robin's permission, Charles quickly stood up and began to tell him what had happened since the Great Serpent Army's fleets began heading south and his decision to confront them. Then he told him about Sakaar confronting an entire fleet alone until support came, and after that he talked about Sakkar's desire to attack the eastern region had it not been for General Gu being able to stop him. Finally, he told him about his decision to attack the northern region and his sentence: I will not stop unless the Lord himself comes.
"..." In front of those successive raging events, Robin did not open his mouth, he just rested his chin on his left hand as he listened calmly until Charles finished explaining the last thing related to Sakaar, so Robin allowed him to sit down with a simple movement and without saying a word.
