Chapter 4 — Watchers in the Dark
The next morning brought with it a quiet fog that clung low over the grounds, curling against the castle's stones like smoke searching for warmth. Harry woke before the others, still dressed, wand gripped beneath his pillow.
He didn't sleep much anymore.
Every time he closed his eyes, memories warred with instincts. Hogwarts in peace was a fragile, alien thing. A lie he didn't yet trust. But here it was—Ron snoring into his pillow, Seamus drooling on his Transfiguration notes, Neville's cactus blooming gently on the windowsill.
He pulled the curtains shut around his bed and cast a silent Muffliato.
From beneath the boards, hidden where only he would think to look, he retrieved a velvet-wrapped pouch. Inside: six galleons, two enchanted coins, a sliver of basilisk fang encased in a stasis rune, and the beginnings of a new map. Not a Marauder's Map—this one tracked danger.
Patterns. Disappearances. Changes in magical density. Tonks had helped him build the prototype. Years from now.
He unrolled the parchment, his eyes scanning for even the slightest spike in magical activity.
Nothing yet.
But it was coming.
"We have three years. That's your window. Voldemort regains a body in June of your fourth year. Until then, he's weak—but not gone."
Tonks sat cross-legged across from him that night, beneath the library's west tower, where only a few portraits lingered and the torches always flickered blue.
"Three years sounds like a long time," Harry said, low.
"It's not," she said. "Not when you're fighting a ghost no one believes in."
They'd met every night since the reveal. Quietly. Strategically. Conversations mapped out with care, cross-referencing timelines, people, actions, and consequences.
"He's still tethered," Harry muttered, "and I still have one inside me."
"You're sure?" Tonks asked, eyes narrowing.
"Yes." He tapped his chest. "I can feel it. Not like I used to. No whispers. But it's there. Quiet. Caged. I think coming back... disrupted it."
Tonks leaned back against the stone wall, fingers brushing her wand. "Then that's priority one. Finding the others."
Harry nodded. "We'll need Slughorn."
Tonks frowned. "Horace Slughorn? The potions master?"
"6th year, he's brought out of retirement. Dumbledore uses me to extract a memory from him—about a certain conversation with Tom Riddle."
"Riddle asked him about Horcruxes."
"Exactly. I'll find a way to speak with him sooner. Meanwhile, we need to secure the diary."
Tonks exhaled sharply. "Ginny. First year."
"I'll take care of it. Subtly. But we watch her. We get ahead of Malfoy. And if I'm right... Dobby will try to warn me soon."
Tonks smirked. "You really have done this before."
His eyes darkened. "Too many times."
Dobby's Warning Came on Schedule.
Harry had baited the hook—an overheard comment about Lucius Malfoy in the Slytherin corridor, and a sugar quill left out on the table in the kitchens. Dobby appeared two days later, wringing his ears and sobbing about great danger and dark plots.
Harry soothed him with promises of socks and freedom that would come early this time.
But he left out the diary.
The fewer who knew, the safer Ginny would be.
The days passed like stones skipping water. Tonks resumed her role as Prefect, blending effortlessly into the flow of seventh year life. But behind the scenes, she was a force: slipping into the Restricted Section under invisibility, collecting notes on dark magical theory, building cover stories in case they were discovered.
Harry, meanwhile, played his part. Obedient third year. Average student. Trouble magnet with the occasional smirk. But he watched.
Constant vigilance.
He kept tabs on Malfoy and his father's owl delivery schedule. Monitored Ginny's moods, waiting for the diary to hook in. Warned Hermione—subtly—to steer clear of it. By mid-November, he was almost ready.
But there was something else.
A pull.
He felt it strongest near the third-floor corridor, where Fluffy had once stood guard, long since removed. The wards were faint, but old. Not from Dumbledore.
From someone else.
Daphne Greengrass.
Harry first noticed her watching him near the greenhouses. Quiet, composed, Slytherin robes impeccably pressed. She said nothing. Just observed, eyes sharp like frost on steel.
Then again in the corridor outside Defense. And once—just once—trailing three steps behind when he cut through the fifth-floor passage he knew no one else used.
Tonks dismissed it. "Probably thinks you're just weird enough to be interesting."
But Harry didn't believe in coincidence. Not anymore.
On a rainy Friday, he cut across the courtyard to intercept her. Alone. No audience. Just the falling mist and the echo of boots on wet flagstone.
"Greengrass," he called.
She stopped, turned slowly. No expression. "Potter."
"You've been watching me."
"You're observant."
He narrowed his eyes. "Why?"
"Why not?"
"That's not an answer."
She tilted her head, voice level. "You don't act like a third year. You disappear into corridors that don't connect. You always know when a teacher's about to round the corner. You watch people. Like you're expecting something."
She stepped closer, lowering her voice.
"I don't care what game you're playing. But be careful. Some of us notice patterns."
She walked away before he could answer.
Harry watched her go, cold knot twisting in his gut.
Tonks Wasn't Happy.
"You think she's a threat?" Harry asked as they met that night in their new spot—beneath the Great Hall, through a wine cellar no one used since the staff stopped serving elf-brewed firewhiskey.
"I think she's dangerous," Tonks said flatly. "But not in the way you're used to. She doesn't act. She waits. That makes her harder to predict."
"I didn't think she'd spot me. Not this soon."
"You're slipping."
"No. I think she's just that good."
Tonks paused, chewing her lip. "We keep an eye on her. If she makes a move—"
"We talk first. We don't jump to war."
She studied him in the low light. "You're still hoping for allies."
"Some battles aren't won with wands," he murmured. "And if I'm right... I'll need her later."
The month ended with a whisper.
Ginny hadn't yet found the diary—but it was close. Malfoy had it. Harry tracked the owl to Hogsmeade. Tonks intercepted the return letter. It was time.
He would take it before it could ever touch her hands.
That night, as Harry stood beneath the black archway of the Owlery, waiting for the perfect moment to intercept the delivery, he felt it again:
That weightless ache in the chest. The sense that something unseen had shifted.
History hadn't changed yet.
But the air was beginning to tighten.
Choices were being made.
Watchers had awoken.
And Harry Potter wasn't the only one remembering things that hadn't yet happened.
