AN: I received some reviews/dms of readers having doubts on if harry and hermione replaced themselves in this new timeline or if they become 2 seperate characters. Hopefully this chapter clears those doubts.

Chapter 4: Blending In and Gathering Intel

The morning sun streamed through the high windows of the Great Hall, casting a golden glow over the enchanted ceiling. Laughter and chatter filled the air as students gathered for breakfast. It was Hogwarts exactly as Harry and Hermione remembered it—but everything felt subtly off.

Because they weren't first-years. Not really.

Harry still struggled with the unsettling disconnect between his seventeen-year-old mind and his eleven-year-old body. His hands were smaller, his voice higher, and his scar, though still faintly throbbing, felt less significant than it had in years. Across from him, Hermione was adjusting her grip on a goblet, turning it in her hands like it was foreign.

"This is so bizarre," she murmured under her breath.

Harry nodded, swallowing a bite of toast. The food tasted the same, the scents and sounds were identical to his memories—but the knowledge that they had lived a full war-torn lifetime beyond this moment made everything feel surreal.

They were back. Not as ghosts, not as observers, but as themselves. Their younger consciousnesses had been completely replaced, leaving only their war-hardened minds inside these small, untested bodies.

"This was our table," Hermione whispered, her eyes scanning the Gryffindor first-years around them. "We sat here, right in this spot, with Ron."

Harry forced himself to nod, though the absence of Ron at their side felt like a phantom pain. They hadn't yet rekindled their friendship with him. Could they? Should they?

"We need to eat," he said finally. "We have a long day ahead."

They focused on their food, doing their best to act natural, but a tension remained between them. It was as if their minds were constantly screaming at them—this is wrong, this is out of place—but their bodies, their surroundings, told them otherwise.

This was their reality now. And they had to blend in.

The first day of lessons was both frustrating and amusing. Everything was too easy—but they had to pretend it wasn't.

In Charms, Professor Flitwick had them practicing Wingardium Leviosa. Hermione, who had mastered it more than six years ago, deliberately hesitated on her wand movements, forcing herself to "learn" at a normal pace. Harry followed suit, though he could see the flicker of irritation in her expression.

"I could do this spell in my sleep," she muttered.

Harry smirked. "And now you have to pretend to learn it again. Welcome to the past."

Potions was another challenge.

Snape swept into the dungeon, his robes billowing, his sharp gaze scanning the room. When his eyes landed on Harry, there was a familiar flicker of disdain—not hatred, not suspicion, just the same quiet contempt he had always harbored for James Potter's son.

"Ah, Potter," Snape sneered, his voice dripping with condescension. "Let's see if you have inherited even a fraction of your mother's talent, or if you will disappoint me as thoroughly as your father did."

Harry fought the urge to roll his eyes. He couldn't react like a battle-worn adult. He had to act like a nervous first-year, or he'd draw suspicion.

"Yes, sir," he muttered, keeping his head down.

Snape's lip curled slightly, clearly dissatisfied with the lack of resistance, but he moved on. Beside him, Hermione gave Harry a quick approving glance. They had to play this right.

This was their life now—playing the role of students while carefully nudging events into place.

After classes, they made their way to the library, where Hermione pulled out a notebook she had conjured earlier.

"We need a plan," she whispered, quill poised over the parchment. "We can't just react to things as they happen."

Harry nodded. "We need to track the key events of each year. The Philosopher's Stone, the Chamber of Secrets, Pettigrew, the Triwizard Tournament…" He hesitated. "Cedric."

Hermione's expression darkened. "We're not letting him die this time."

Harry exhaled slowly. "Agreed."

She tapped her quill against the parchment, thinking. "Quirrell is our first concern. We need to monitor him closely, but we can't stop him too soon. If we do, Voldemort might adapt faster than we're ready for."

Harry frowned. "How do we watch him without drawing attention?"

Hermione smirked. "We're first-years. No one notices first-years."

Harry chuckled. "That's disturbingly true."

That night, once the common room had emptied, they slipped out. The corridors were dimly lit, the flickering torches casting long shadows along the walls.

They moved silently, sticking close to the walls as they made their way toward the dungeons.

"If Quirrell is already meeting with Voldemort, we need to know," Hermione whispered.

Harry nodded, his grip tightening on his wand.

As they neared the dungeon entrance, they heard footsteps. Hermione grabbed Harry's sleeve and pulled him into the shadows.

A figure emerged from the darkness—Quirrell. He was tense, muttering to himself as he slipped into a side chamber. They exchanged a glance before inching closer, careful not to make a sound.

Then they heard it.

A hiss—low, serpentine, unnatural. A voice Harry knew all too well.

"Your progress is disappointing, Quirinus," the voice of Voldemort rasped.

Harry's blood ran cold. Hermione's fingers gripped his wrist tightly, and he knew she was thinking the same thing.

The words sent a chill through Harry's spine. He had faced Voldemort countless times, but hearing that voice again, so soon, in such a fragile moment of their journey—it was terrifying.

"We need to move," Hermione whispered. "If we stay too long, we risk being caught."

Harry hesitated, the urge to act clawing at him. But she was right. They weren't ready for a direct confrontation—not yet. He nodded reluctantly, and together they crept away, unseen and unheard.

As they returned to the common room, slipping into their beds as if they had never left, Hermione whispered one last thought in the darkness:

"This is the first real test. And we can't fail."
