The Secret-Keeper betrayal

The Broken Trust
The Fidelius Charm
James and Lily trusted Peter Pettigrew as their Secret-Keeper. They believed he would die rather than betray them. But he was already working for Voldemort.
The Consequences
Pettigrew's betrayal led to the Potters' death, Sirius's imprisonment, and twelve years of suffering. Trust was shattered.
The Lesson
Trust is fragile. It can be misplaced. The story explores how trust can be earned and broken.
Sirius's false accusation

The Wronged Man
The Frame
Sirius was believed to be the traitor because of Pettigrew's staged death. He was imprisoned without trial. The wizarding world trusted the false evidence.
The Isolation
Sirius lost his friends, his freedom, and his reputation. He was assumed to be a murderer. Only he knew the truth.
The Restoration
When the truth comes out, trust is restored. Harry believes him. Dumbledore supports him. The theme is that truth will eventually prevail, and trust can be rebuilt.
