The very idea that Balthier might have had to let go made David look truly distressed. Clearly Balthier has underestimated just how deeply David loved him. It wasn't an easy thing for him to come to feel, or to admit to.

"Demons are... I fear them more than almost anything. And the idea of you facing one..."

God he shudders. Balthier could probably do it, David believed in the force of his will. But he also feared that if Balthier didn't win, he'd lose his heart to a demon in a whole new way.
