"We don't know what happened sir…us three can't remember anything," said Harry.
"Well Harry, I do know what happened last night," said Dumbledore.
"Can you help us and tell us what happened then sir?" asked Hermione.
"Very well, I shall," said Dumbledore.
Chapter 4 – The night before
"Last night, some-one had seemingly used the polyjuice potion to change into a Gryffindor," began Dumbledore
"Who was the person that changed into a gryffindor?" asked Ron.
"And then he snuck into the Gryffindor common room and put something in your drink," said Dumbledore, ignoring Ron.
"He spiked our drinks?" said Hermione shocked.
"Yes, but he did not exactly spike you, but he did… What he put in was a sort of drug that makes you fall in love with one of your best friends, in this case, Harry and well, you know the rest," said Dumbledore.
"But why did hehave to spike mine?" asked Ron confused.
"Well, he put a different drug in yours, he put in a drug that makes you forgot what happened," said Dumbledore.
"And you know who it was?" asked Harry.
"Yes…yes I do," answered Dumbledore.
"Who was it?" asked Hermione standing up.
"You will know soon enough…now, off you go," said Dumbledore standing up. Harry, Ron and Hermione stood up and went down the moving stairs once move.
"Do you actually think he knows what happened last night?" said Ron, as they walked into the common room.
"He must know if he knows that they used the polyjuice potion and drugged us, then he must know what happened last night," said Hermione, sitting in one of the armchairs in the common room.
"But why didn't he tell us who it was?" asked Ron, plunking himself onto the sofa, in front of the fire.
"I don't know, but we must find out who drugged us and why," said Harry standing in front of the fire and starring into it.
"But, where do we start? I mean, who stated at Hogwarts for Christmas?" asked Hermione.
"Why don't we start at Houses," began Ron, "Gryffindor… Us three were the only ones to stay."
"Right," said Hermione confused.
"Hufflepuff… Susan Bons and I don't know who else?" asked Ron. Harry shrugged while Hermione did nothing.
"Ravenclaw-"
"Cho and who else?" finished Harry.
"I think that's it for Ravenclaw, but… Slytherin," said Hermione with a smirk.
"That won't be hard to figure out who stayed," began Ron sarcastically, "Crabbe, Goyle Malfoy-"
"Malfoy! It must have been him," said Hermione.
"But we don't have any proof," said Harry.
"We will in a minute," said Hermione standing up and making her way out of the common room.
"Hermione!" shouted Harry and Ron at the same time.
"Hurry up," echoed Hermione's voice.
