Severus puked. Then the last ghost arrived. He saw the ghost reflected in his puke. He scrambled away from the ghost. He was horrified by how much he felt. How painful his chest was beating. "I don't want to; just go," Severus whispered.
He had faced the ghosts of his past and present, confronting painful truths and memories. Now, as he stood alone, a chill filled the air once more, and a new figure materialized before him: the Ghost of his Future. "I am the Ghost of the Future," the last ghost whispered. "Come with me, and see the path your choices will lead you." He struck out his hand. "Don't you want to know what you need to know?"
Severus felt terrified. He was frozen in his fear for a moment. The moment almost felt like forever. His mother's warning was going through his mind.
"Are you sure, Severus?" The last ghost started to turn away and let his hand fall to its side. It started to fade. "I guess I misjudged you for being brave."
Suddenly, Severus pushed all his thoughts, feelings, and everything else away. He felt clarity again as he stood up and grabbed the ghost's hand just in time. For a moment, Severus thought he might have been too late, but then his surroundings changed again.
He found himself standing in a dark, foreboding chamber. The air was thick with tension. Severus realized he was witnessing a scene from a future he feared yet knew was inevitable. He almost could not see what was happening as he felt so much pain on his left underarm. His vision was blurred. He saw himself. And he saw Him. He saw himself double over in pain at the Dark Lord's feet. His pale arm is stuck up towards the Dark Lord, who holds onto it. Severus saw the dark mark being etched into his reddening skin.
There he was, branded with the Dark Mark, a mark of allegiance to Voldemort. The pain of betrayal and submission seared through him as he watched his future self. He saw himself surrounded by hooded figures.
"No," Severus whispered, his voice hoarse with despair. "I never wanted this."
But then something shifted. A new scene began to unfold, one that chilled Severus to his core. He saw himself as a Death Eater, standing amidst the ruins of a Muggle village, flames licking the night sky. He watched in horror as his future self tortured Muggles, their screams echoing in the darkness.
"No!" Severus cried out, recoiling from the brutality he witnessed. "I would never..."
The ghost's voice cut through his turmoil. "This is a possible future, Severus. It is the future you are currently heading for."
Severus felt sickened by what he saw—the destruction and suffering caused by his own hands. The scene shifted again, and he found himself in a fierce battle. Members of the Order of the Phoenix confronted him, their faces grim with determination. Spells flew through the air, and Severus fought back.
The scene shifted, and Severus found himself in a different place—a wedding ceremony. Lily Evans stood before him, radiant in white, as she exchanged vows with James Potter. Happiness and love radiated from her. A stark contrast to the darkness that had enveloped Severus's own life.
"Lily..." Severus murmured, his heart aching with longing and regret. "I could have..."
The ghost nodded silently, understanding the unspoken words. "You made your choices, Severus."
The scene changed again. Severus saw Regulus Black, younger and defiant, declaring his loyalty to Voldemort's ranks. Regulus looked nervous. Severus saw the Dark Lord declare Regulus dead and a coward for trying to flee.
"He died trying to undo what I pushed him to be," Severus said bitterly. "I pushed him towards the Dark Lord, thinking it was the path to power."
The ghost's gaze was steady. "You can still change, Severus. The future is not set in stone."
Severus saw flashes of Christmases spent with Lucius and Narcissa Malfoy. Their opulent home is adorned with decorations and warmth. He witnessed the birth of their son, Draco. He witnessed Lucius's solemn request for Severus to be Draco's godfather.
"I cared for them," Severus admitted quietly. "But my choices tainted everything."
The ghost nodded again, leading Severus through more scenes. He saw himself overhearing a prophecy about a child who could defeat Voldemort. He saw the Dark Lord's obsession with the prophecy. Severus plea to the Dark Lord to spare Lily. Severus's desperate plea to Dumbledore to keep Lily and her family safe.
"I begged him," Severus said, his voice cracking with emotion. "I begged Voldemort to spare her."
The ghost led Severus through the harrowing events that followed: Dumbledore's grim revelation of James' and Lily's deaths and the survival of her son, Harry. Severus felt the weight of his failure and his promise to Dumbledore echoing in his soul.
"If you loved her, you must protect her son," Dumbledore's voice echoed in Severus's mind.
The scenes ended with Severus's final moments in the Shrieking Shack. His last sacrifice was to ensure Harry's survival. To redeem the mistakes that haunted his life.
"I died trying to make amends." Severus said quietly, his eyes filled with regret and resignation. "But was it enough?"
The ghost turned to him, its presence comforting yet haunting. "The future is shaped by the choices we make, Severus. Your choices, both good and bad, have led you here."
Severus nodded slowly, absorbing the gravity of his journey. "I see it now. My past, present, and future are one. They are the tapestry of my life."
"You have seen the consequences of your actions," the ghost said. "Now, what will you do with this knowledge?"
