The deep quiet of the Undercroft was broken only by the distant drip of water. It was well past midnight, the castle's usual nocturnal hum silenced, leaving the ancient chamber cloaked in profound stillness. The air was cool, damp, and held the faint, lingering scent of old magic and Sebastian's presence.
And there he was, slumped over the Pensieve, quill scratching furiously across his journal, his face drawn. The faint glow of the nearby Pensieve illuminated his intense concentration. He didn't stir at her entrance.
"I knew I'd find you here," she murmured, her voice thin with exhaustion.
Sebastian flinched, pulling his head from his notes with a gasp. His head snapped up, his eyes wide and wild, his mind still consumed by the frantic notes he'd been scribbling in his journal. He scrambled back, stumbling over his own feet, before quickly regaining his composure. He ran a hand through his perpetually tousled hair, trying to smooth it down, trying to appear normal. "What are you... I mean, hey," he said, his voice a little strained. He quickly noticed the dark circles under her eyes, the way her shoulders drooped, the unnatural pallor of her skin. A quite contrasting look to what she had a couple of days ago. "Are you alright? You look... exhausted."
She let out a sigh that seemed to carry the weight of days. "Exhausted is an understatement. I'm utterly spent, Sebastian." She ran a hand over her face, rubbing her temples. "I just... I can't sleep. Every time I close my eyes, every time I drift off, it's the same thing."
Her voice dropped to a raw whisper, the words tumbling out in a rush, unfiltered by her levels of exhaustion. "The nightmares. They're relentless. And I just... I can't sleep properly." She took a shaky breath, the vulnerability stark on her face. "Garreth's been brewing me different things to help, still testing, you know," she admitted, her voice barely audible. "It helps... a little. But I still hear them, even when I'm half-asleep. I just need to turn it off, Sebastian. To make it stop." Her gaze met his, desperate and pleading.
A sharp, unwelcome prickle tightened Sebastian's chest, a feeling he refused to name. Garreth? Brewing her potions now? He forced a casual, mocking grin. "Garreth? Really? Well, it's a miracle your hair hasn't changed color, or your stomach hasn't exploded yet." He tried to sound light, even amused, but a muscle twitched in his jaw.
She let out a soft snort of amusement, shaking her head. "You're ridiculous, Sebastian" she murmured, a faint smile playing on her lips.
"I'm serious, Professor Sharp would agree with me," he said, his tone bitter, "But anyway… what brings you here, then?"
Her eyes met his, a strange, hopeful glint in their weary depths. "Well, the other night I had a very decent sleep. The best sleep in days, to be honest. It was the night I fell asleep right here, in the Undercroft, while you were... studying." A faint, ironic chuckle escaped her. "Maybe this place has some secret charm, or something. I was hoping... I could try to sleep here again tonight."
A horrifying realization twisted in his gut, a cold, sickening dread displacing all other thoughts. He remembered the vial, the clear liquid, the subtle flick of his wrist. He remembered slipping that powerful sleeping draught into her tea, hoping to give her a night of forced oblivion. And now she was here, believing this place held the key to her rest, utterly unaware of his deception.
"Have you... have you tried a sleeping draught?" Sebastian asked, his voice rougher than he intended, a forced innocence in his tone.
She sighed, a fragile sound. "I'm trying to stay away from those, to be honest. Sleeping draughts, I mean." Her voice was quiet, tinged with a painful honesty. "It's not that I can't sleep without them, not really, but I just... I haven't been able to. And over time, they just lost their effect, no matter how much I took. Now they barely keep me calm."
Was this it? Was this why it took her so long to finally fall asleep that night when he slipped his powerful sleeping draught in her tea? Sebastian felt a profound ache of guilt. She was struggling, truly struggling with this, and she hadn't told him. His own desire to pursue a cure for Anne and knowledge had blinded him to the silent battle she was fighting. She used to tell him everything. And the crushing irony—he had added to her burden without knowing.
"Why didn't you tell me about it?" he asked, his voice rough with a mix of genuine concern and his own self-reproach.
She shrugged, a weary movement. "You're busy. With the Pensieve. Catching up with assignments. With Quidditch. We have tests coming shortly…"
Sebastian just nodded sadly. "I know… But still… You can tell me anything..."
A weak, exhausted smile touched her lips, a fragile light that twisted his gut. He didn't deserve that. Not after what he'd done. Not after what he was becoming. He offered a weak, exhausted smile that he knew didn't reach his eyes.
"Perhaps," Sebastian said, his voice thoughtful, forcing a calm he didn't feel, "a cup of my secret blend would help. Maybe that's what truly helped you the other night?" He offered a brittle, fake smile, hoping it looked convincing.
She looked at him, her tired eyes softening with gratitude. "I'd like that, Sebastian. Thank you." Her gratitude was a fresh stab of guilt, sharp and cold. She was thanking him, trusting him, for something he was doing deceptively. He was adding to her burden.
He moved to the small, makeshift brewing station in the Undercroft. His hands, usually so steady, trembled slightly as he measured out calming herbs. He glanced back at her, ensuring her gaze was not on him. With a swift, discreet movement, he uncorked a familiar vial and added a few drops of his strong sleeping draught to her cup. He rationalized, the thought a frantic scramble in his mind, that this was the last time. It was just to help her sleep, just until he could find another way—a true cure for these relentless nightmares. The soft scrape of her chair as she settled back at the table made him jump, a jolt through his already frayed nerves.
"So, how's the research going?" she asked, her voice a soft hum of curiosity, oblivious to his actions.
"Progressing," he replied, his voice still a little tight. "I think I know what curse Rookwood used against Anne. Or at least the pronunciation. I just need to find out more about it, because it's an ancient language."
He placed the steaming cups on the table, along with a plate of biscuits he had been snacking on. They drank in silence for a moment, the warmth of the tea a stark contrast to the cold weight in his heart. Sebastian tried not to look at her too obviously, but he couldn't help an occasional, guilt-ridden gaze. He pretended to read a Potions book, his eyes scanning the pages without truly registering the words. Soon, her eyelids began to droop.
"Mmm, this is nice," she murmured, her words slurring slightly. "Is this... lavender tea? That’s your secret recipe?"
Sebastian's heart clenched. "Lavender is one of the ingredients," he managed, his voice gruff.
"You know… Ominis is getting suspicious," she rambled, her eyes half-closed, her voice slurring further with sleepiness. "He knows you've been spending too much time here. But I told him..." she yawned. "I told him you're probably close. Close to finding the cure. For Anne." Another yawn. "And I told him that I've been helping you catch up with your assignments."
Sebastian felt a fresh wave of profound guilt crash over him. "Thanks," he just managed to say, his voice cracked with guilt. She trusted him. She was lying for him. And he was lying to her, again, about something so fundamental to her well-being. The bitterness of his choices choked him.
She yawned, a wide, languid stretch, and tried to stand. She stumbled, swaying dangerously. Sebastian was there in an instant, his arm shooting out to steady her. He gently guided her to the long, velvet couch he often slept on, and she collapsed onto it, already half-asleep. He carefully pulled a blanket, discarded on the back of the couch, over her.
"Goodnight, Sebastian," she mumbled, her eyes already closed, her breathing evening out.
"I'm sorry," he whispered, his voice cracking, as he watched her sleep. He was sorry for the lie, sorry for the burden he'd placed on her, sorry for everything. And he was utterly, terrifyingly alone with the weight of it all.
