This episode is the start of the final stretch towards the location of Laplace box. If you expect for the crew of Nahel Argama and Neo Zeon would get along even after the previous incident then that's a pretty naive thinking. The atmosphere is so tense that you can cut it with a knife, even after Full Frontal's true intention is revealed. The speech was just a mirror of something that Char would say if the Zabis(no offense for Mineva) wasn't such an ass and he plans to somewhat carry on his father's legacy.
