The Trajectory of Ice Breaking

The biting January wind still howled, and the Hogwarts Express, carrying students returning from the holidays, roared back, filling the castle with noise once more. The quiet, almost secluded understanding of the break had to face the disturbances of reality again with the return of the crowds.

Snape almost immediately donned his heavy armor of defense again. In the Great Hall, in the corridors, he became gloomy and reclusive once more, meeting any gaze directed at him with cold indifference, and completely ignoring Lin Yanqing. It was as if the person who had shared research results in the library during Christmas break, even gruffly reminding the other to "use potion ingredients sparingly," was merely an unreal phantom.

But Lin Yanqing could feel through the Contract that something had changed beneath this armor. Beneath the cold, stagnant water, there was a subtle "certainty." Snape no longer felt the pure, constant anxiety about the existence of this bond as he had before. He seemed to... accept its continued existence, as naturally as breathing, even though he still detested it.

In the first Potions class of the new semester, Professor Slughorn, beaming, asked the students to present their holiday research. Most students presented common potions of various colors and varying purity. When it was Snape's turn, he walked forward silently and placed the small crystal vial before Slughorn.

"Merlin's beard!" Slughorn uncorked the bottle and took a gentle sniff, his round face showing extreme shock and delight. "This luster! This purity! A flawless Moonlight Calming Potion! Severus, my boy! This is... this is the work of a master! Slytherin gets fifty points! No, a hundred!"

The classroom erupted in a commotion. The Moonlight Calming Potion was a complex potion that few even at NEWTs level could perfect! James Potter's smug smile froze, Sirius Black's nonchalant expression vanished, and his eyes became serious. Lily Evans, on the other hand, was purely astonished and full of admiration.

Snape faced the gazes of everyone, his face expressionless. He merely nodded slightly, as if this earth-shattering achievement had nothing to do with him. But Lin Yanqing could detect, deep within him, a faint ripple of accomplishment spreading, though he quickly suppressed it.

However, the successful demonstration brought new trouble. Slughorn's favoritism towards Snape became undisguised, even publicly expressing after class his hope that Snape would consider joining the Slug Club in the future. This attracted more envious or probing glances, especially from students of pure-blood families within Slytherin.

One evening, as Lin Yanqing returned to the Ravenclaw tower from the library, he heard hushed voices in a deserted corridor.

"...just a half-blood, got lucky." A gruff voice said; it was Crabbe.

"Professor Slughorn is praising him too much," Goyle agreed. "And that Ravenclaw... there must be something shady going on between them..."

"Shut up!" A cold voice, laced with suppressed anger, interrupted them. It was Snape.

Lin Yanqing stopped, hiding in the shadow of a pillar. He saw Snape standing before Crabbe and Goyle, his face paler than usual, his dark eyes burning with a cold flame. Though he hadn't drawn his wand, the aura emanating from him made the two much larger boys instinctively take half a step back.

"My affairs are none of your business," Snape's voice was not loud, but it whipped through the air like a lash. "If I hear any more... I don't mind letting you taste whether my newly developed potions have only 'calming' effects."

A flicker of fear crossed Crabbe's and Goyle's faces. They mumbled a few indistinct words and slunk away resentfully.

Snape stood alone, his chest rising and falling slightly. Through the Contract, Lin Yanqing could feel the surging emotions within him, a mixture of offended anger and a twisted sense of exhilaration from having defended some boundary.

He didn't leave immediately but stood there for a few seconds, as if calming himself. Then, he suddenly turned his head, his gaze precisely locking onto the pillar where Lin Yanqing was hiding.

He said nothing, just looked. The corridor was dimly lit, and Lin Yanqing wasn't sure if he had actually seen him.

But the next moment, Snape raised his hand and, as if unconsciously, very lightly touched the collar of his black winter robe. Then he turned and left quickly.

Lin Yanqing stepped out from the shadows, looking in the direction Snape had disappeared, understanding dawning in his heart. The gesture of touching his collar, so subtle it was almost imperceptible, was a clear signal. He was telling him in this way: I know you're here, and what I just defended also includes the boundary between "us" that outsiders cannot question—even though this boundary is defined by a Contract he detests.

It was a declaration of a cold alliance.

A few days later, in Defense Against the Dark Arts class, the new professor (a wizard who always spoke with a slight tremor and seemed somewhat neurotic) was explaining how to identify and defend against a common deceptive magical trap. The lesson was somewhat dry, and many students began to drift off.

Lin Yanqing noticed that while Snape appeared to be listening intently, his fingers were unconsciously rubbing his wand under the desk, conveying a sense of boredom through the Contract, like "this content is too basic," and a hint of creative desire. He seemed to be conceiving or refining a spell in his mind.

Just then, the professor asked them to pair up and practice a simple counter-charm against confusion. The classroom immediately became a chaotic scramble for partners. James Potter naturally paired with Sirius, and Lily with another Gryffindor girl.

Snape remained alone in a corner, as if the surrounding liveliness had nothing to do with him.

Lin Yanqing also didn't actively seek a partner. He stood still, his gaze calmly directed towards Snape.

This time, Snape didn't immediately look away or emit a repelling aura. He raised his eyes, his dark pupils meeting Lin Yanqing's for a full three seconds. There was no sign of friendliness in his gaze, only a near-scrutinizing assessment.

Then, as the professor began to urge the remaining students to pair up quickly, Snape subtly, almost imperceptibly, tilted his head towards the empty seat beside him.

A movement so small it was almost nonexistent.

Lin Yanqing walked over without hesitation and sat in the empty seat next to Snape.

There was no verbal communication throughout the entire process. Slytherin and Ravenclaw, two students who seemed to have no connection, thus formed a pair under the watchful eyes of everyone.

James Potter immediately shot them a look of astonishment and displeasure. Lily also appeared somewhat surprised, but her eyes held more curiosity.

Snape ignored all the gazes and simply said coldly to Lin Yanqing, "The core of the spell lies in focusing your will, not the intensity of your magic. Let's begin."

His tone was like stating an objective fact, devoid of emotion.

"Okay," Lin Yanqing replied calmly.

They raised their wands and began to practice. The spell's light flickered steadily between them. While their coordination wasn't exactly seamless, there was no hesitation or error. They moved like gears in a precise machine, operating in a cold, efficient rhythm.

Through the Contract, Lin Yanqing could feel that what emanated from Snape was no longer rejection or tolerance, but a state of pure focus on problem-solving. He regarded Lin Yanqing as a qualified "practice partner" who wouldn't hold him back, nothing more.

But that was enough.

For Severus Snape, allowing someone to approach his field of study so closely and forming a temporary alliance in public was itself a huge, silent transformation.

The ice had not melted, but a clear path had quietly formed upon it, pointing towards an unpredictable future.
