Authentic exhaustion. Not the glamorous, sweat-glistening kind, but the messy, frustrated, 'I want to quit' kind. The trait is their honesty in that moment. They might cry, rage, or simply sit in silence. But they don't romanticize the struggle. Showing the real emotional and physical toll makes their decision to continue—not because it's easy, but because it matters—the most powerful character beat of all.
