The Serpent Prince

The next morning, the castle buzzed with its usual energy, the early light casting long shadows through the arched windows of the Great Hall. Alex moved through the motions of breakfast, his mind preoccupied with the events of the previous night. The cryptic words of the merfolk replayed in his head: "One of them sleeps in the depths, bound by time and tides."

Lily had been surprisingly understanding, even eager to involve herself. Her mix of charm and sharp wit made her a natural ally, but Alex wondered if her interest in the mystery ran deeper than simple curiosity.

"You're thinking again," Imogen said, sliding into her seat across from him. She was holding a copy of the Daily Prophet, the edges of the newspaper slightly damp from the morning dew.

"I wasn't aware that was a crime," Alex replied, raising an eyebrow.

"It's not," she said, smirking. "But you have that look—the one that says you're up to something. Care to share?"

"Nothing worth mentioning," Alex said smoothly.

Imogen studied him for a moment, her sharp eyes narrowing. "You know, the whole 'mysterious prince' thing might work on most people, but I'm not most people."

"Noted," Alex said with a faint smile.

Before Imogen could press further, Malcolm arrived, his hair sticking up in all directions and his tie crooked. He plopped into the seat beside Alex, looking harried.

"Why do mornings exist?" Malcolm grumbled, reaching for a slice of toast.

"To keep you humble," Imogen quipped, earning a glare from him.

"You're both very cheerful today," Alex observed, his tone dry.

"Just trying to survive," Malcolm muttered through a mouthful of toast. "We've got Potions first, and Slughorn said something about starting on antidotes. I'm doomed."

"You'll be fine," Alex said, though he wasn't entirely sure.

Imogen smirked but didn't comment, her attention returning to the newspaper.

A Stirring in the Dungeons

Potions class that morning proved more challenging than usual. Professor Slughorn had indeed introduced antidotes, and the task of brewing one to counteract a simple sleeping draught left many students struggling. The room was filled with the clinking of glass vials, the soft bubbling of cauldrons, and the occasional puff of smoke as someone's mixture went wrong.

Alex worked methodically, measuring each ingredient with precision and following the instructions on the blackboard to the letter. Beside him, Malcolm was having significantly less success.

"Why is mine purple?" Malcolm hissed, staring into his cauldron with growing panic. "It's not supposed to be purple, is it?"

"It's not," Alex confirmed, glancing over. "You added the valerian root too early. Stir clockwise three times and add a pinch of powdered bezoar."

Malcolm scrambled to follow the advice, his hands shaking slightly as he added the bezoar. The potion shifted from purple to a pale blue, though it still didn't match the emerald-green hue described in the instructions.

"Close enough," Alex said quietly.

Malcolm sighed in relief. "You're a lifesaver."

"Don't thank me yet," Alex said, returning to his own potion.

By the end of the lesson, Alex's antidote earned him another approving nod from Slughorn. Malcolm managed to avoid disaster, though his potion received a polite but unenthusiastic critique.

As they packed up their supplies, Imogen sidled up to Alex, her smirk firmly in place.

"You really enjoy being the overachiever, don't you?" she said.

"I enjoy doing things well," Alex replied.

"And here I thought you were just trying to impress Slughorn."

Alex gave her a sidelong glance. "What makes you think I need to impress anyone?"

Imogen laughed softly. "Touché."

The Lake's Echoes

Later that afternoon, Alex found himself drawn back to the edge of the Black Lake. The castle grounds were quiet, most students opting to spend their free time indoors or in the bustling courtyard.

He stood at the shoreline, his hands clasped behind his back as he gazed out over the water. The surface was calm, reflecting the gray sky above, but Alex could feel the tension beneath it.

"Back here again?"

The voice startled him, though he didn't show it. Turning, he saw Lily approaching, her Gryffindor scarf trailing behind her in the breeze.

"I wasn't expecting company," Alex said.

"Too bad," Lily replied with a grin. "I was curious to see if you'd come back."

"And now that you've confirmed it?"

"I'm staying," she said simply, stepping up beside him.

For a moment, they stood in silence, the sound of the water lapping gently against the shore filling the space between them.

"You're really serious about this, aren't you?" Lily said finally, glancing at him.

"I am," Alex admitted. "There's something in the lake—something the merfolk warned me about. I can't ignore it."

Lily tilted her head, studying him. "You're different, you know. Most people wouldn't bother. They'd hear 'danger' and back off."

"And what about you?" Alex asked, meeting her gaze.

She smiled faintly. "I think danger makes life interesting."

Alex's lips quirked upward. "Then we're in agreement."

Lily's smile widened, but before she could respond, a faint ripple appeared on the lake's surface. Both of them turned their attention to the water, their conversation forgotten.

The ripple grew stronger, spreading outward in concentric circles. Alex narrowed his eyes, his hand moving instinctively toward his wand.

"What is that?" Lily whispered, her voice barely audible.

"I don't know," Alex murmured.

The water shimmered, and for a brief moment, something dark and massive shifted beneath the surface. The faint hum Alex had heard the night before returned, low and resonant, vibrating in his chest.

Then, as quickly as it began, the disturbance faded. The lake returned to its stillness, leaving Alex and Lily staring at its surface in silence.

"That," Lily said after a long pause, "was not normal."

"No," Alex agreed, his voice steady despite the tension in his chest. "It wasn't."

Lily turned to him, her expression serious. "Whatever's down there, it's not just some old creature. This is… bigger."

Alex nodded slowly, his mind already racing with possibilities. "Then we'll have to be ready for whatever comes next."

Lily smirked faintly, though her eyes were sharp. "You know, most people would be terrified right now."

"Most people aren't me," Alex said evenly.

"Clearly," Lily said, her grin returning. "Guess it's a good thing I'm not most people either."

As they walked back toward the castle, Alex felt the weight of the lake's mystery pressing heavier on his shoulders. The water had stirred, and whatever lay beneath was starting to wake.

And Alex intended to be ready when it did.
