Well...Harle is special, a creation of the dragons, so it would think different from them. Her love for Serge being a good example. All I mean is that when you defeat Fate, you see the dragons speak the same sentence part by part. The second to last dragon says, "Now, for all humans..." then the last dragon says, "I shall make you bleed!". So it kinda sounds like a single entity saying it, you know? Not to mention they all say the same things, and express themselves the same way when you meet them.
