Yeah, Vergo searched for a sword he doesn't have because he is a brainlet, with Monet pointing out that he was a brainlet for searching for a sword he doesn't have, since he is not a swordsman and Vergo agreeing that he is a brainlet because he searched for a sword he doesn't actually have, since he is not a swordsman.
And the only bigger brainlet than Vergo is the one asking whether Vergo is a swordsman after Vergo admitted he was a brainlet for confusing himself for a swordsman.
