In the process of freeing Paul, Aura says a line which begins with "which will never happen" but that didn't relate to Claude angrily asking why 'Paulina' reverted to being a man or to Aura stating she no longer requires his patronage. I assume it relates to something one of them says if Aura graduates instead of putting on her uniform just long enough to sneak behind a bush and making a beeline straight for the boss.
