Saint-14 in the infinite forest, the Vex simulation, alone — the legendary Titan who saved the Osiris the Vex captured by walking into a trap that consumed him. No Light, no Ghost, just him: the speech is the distillation of what the Titan class is for in Destiny's fictional ecology. Not the Light's power or the Ghost's intelligence, but the person themselves, the will that existed before the resurrection and persists through it. And that was enough is the game's most quietly heroic statement.
