Harry put two and two together. His scar hurting in the forest could mean one thing. The creature was Voldemort, and if the Unicorn blood is keeping him alive, for now, he's after something much much stronger. The stone.
At this point, his and Hermione's research has concluded that the item hidden in Hogwarts is the Philosopher's Stone. And it makes sense that Voldemort would want it. This is how he comes back from… the half dead?
"As long as Dumbledore's around, there's nothing for us to worry about…" Hermione reassured him.
"But, Snape!" Harry countered.
"Snape can't do anything while Dumbledore's around." Hermione insisted. "Plus, as long as Hagrid hasn't told anyone how to cross Fluffy, there's nothing to worry about."
For the next week, that's what all of their conversations were like. They did not discuss the stone, however, in front of anybody else. Whenever Ron, Draco, or Neville were around, they changed the subject.
Then came finals. That distracted Harry from the stone, Snape, and Voldemort a little bit. Once these were done, it was time to celebrate. After his last final- History of Magic, he headed to the pond, where he just laid there under the bright clear skies, enjoying the nice weather, with Draco and some other Slytherin first-years.
"Ahh, that's nice." Harry said, taking a sigh of relief, and closing his eyes. That feeling of relief, however, did not last long, as he felt stabbing pain in his scar. His hand jumped to his forehead.
"Harry?" Draco sat up, visibly concerned. "Are you okay?"
"Yes." Harry said, unconvincingly. "I need to find Hermione." He stands up, and runs to where he knew he would find her. The library.
"Hermione!" He barged in, causing Hermione to look up from her book. Now that finals are over, it was just Hermione in there, and the librarian who shushed him. "My scar." He said, lowering his voice and sitting down beside her.
"That could mean anything…" Hermione tried to be reassuring, but her facial expression suggested otherwise. "Again, the only one who knows how to pass through Fluffy is Hag…" she started saying, before Harry interrupted her.
"Unless…" he started saying, but then he stopped. His eyes widened in horror. "We gotta go find Hagrid!"
"Unless what?" Hermione asked, but Harry was already gone. She followed him.
"Hagrid!" He barged into the hut, just as he did into the library.
"Hey! Harry! Hermione!" Hagrid was happy to seem them as always. "I was just about to make tea."
"The egg guy from Hog's Head." Harry rushed. No time for tea. "He seemed to be particularly interested in Fluffy, you said?"
"I mean who wouldn't be? You don't see a three-headed dog everyday, now do you?"
"Did you tell him how to pass through Fluffy?" Harry asked, urgently.
Hagrid seemed to take offense at this question. He frowned. "Of course not! I would nev-" He started saying, and then stopped. His frown turned to an "I shouldn't have said that" expression.
"What did you tell him, Hagrid?" Hermione asked, way more patiently than Harry would've.
"I told him that taking care of Fluffy is a piece of cake, all you need to do is play him some music, and he'll fall asleep."
Before Hagrid finished his sentence, Harry was already out the door.
"Wait, Harry!" Hermione tried to follow him.
