As Ron continued to regale Daphne with tales of Harry and the Potters, her mind raced, connecting the dots between their stories and Ron's predicament. Suddenly, a realization struck her like a bolt of lightning.

"The Fidelius Charm!" Daphne exclaimed, her eyes widening with excitement. "Ron, I think someone has placed you under the Fidelius Charm, and I'm the only one who can see you because I'm the Secret Keeper!"

Ron's eyes widened in disbelief as he processed Daphne's words. The pieces of the puzzle were finally coming together, and hope began to flicker within him. "Are you sure, Daphne? Could that really be it?"

Daphne nodded, her voice filled with determination. "Yes, Ron. It makes sense. The Fidelius Charm hides a person or a location from those who are not made privy to the secret by the Secret Keeper. And if enough people know the secret, the curse is lifted."

Ron's heart raced with anticipation. The notion that there might be a way to break free from his invisible prison filled him with renewed hope. "So, all we need to do is spread the secret, let people know that I exist?"

Daphne nodded, her eyes shining with a newfound purpose. "Exactly. We need to tell as many people as possible about you, Ron. Once the secret is out, the curse should be lifted."

Without wasting another moment, Daphne and Ron embarked on a mission throughout Hogwarts. They approached students, professors, and even the ghosts, sharing the secret of Ron's existence. At first, many were skeptical, unable to comprehend how someone could be invisible and yet standing right in front of them. But as more people vouched for Ron's presence, curiosity and belief began to spread.

Whispers and conversations echoed through the halls, drawing the attention of students and staff alike. Ron watched in awe as the once-ignoring gazes turned into curious stares and welcoming smiles. It was a surreal and heartwarming experience for him to finally be seen and acknowledged.

And then, it happened. As the news reached a critical mass, Ron felt a surge of energy coursing through him. The Fidelius Charm began to unravel, like a veil slowly lifting. He looked down at his hands, his body, and saw himself materialize before his own eyes.

"I'm visible!" Ron exclaimed, his voice filled with joy and elation.

Daphne beamed at him, her eyes shining with pride. "We did it, Ron! The curse is broken!"
