The next evening, at Sally's urging, they meet in the dilapidated teacher's lounge, this time in addition to Harry and Ron, there is also a girl with brown hair that is very fluffy and a little messy, and Harry introduces her as one of the protagonists of the incident, Hermione Granger.

After listening to the trio tell what happened to them, Sally had more thoughts about the incident. Harry talks about the Quidditch Tracing that Snape had confiscated and decides to try to get it back, but neither Ron nor Hermione agrees with him going, but he goes anyway, and after a while he comes back breathless, not with a book, but with a big secret.

Harry told the trio everything he saw. "Do you know what that means?" and finally he said, "on Halloween, he wanted to pass by the big dog with three heads! we saw him, and he was going there, and he was looking for something that the big dog guarded! I bet with my broomstick that he let the troll in, in order to distract people." ”

No, the man who wanted to take something like that was Professor Quirrell, and Professor Snape disrupted his plans. All the things in Sally's mind had finally been cultivated into a complete line, but she couldn't say, not to say that Harry Ron was now full of prejudice against Professor Snape, and she had promised Professor Snape to keep the matter a secret.

Sally stood up and left the teacher's lounge without saying a word. The three Gryffindians were left looking at each other.

"It's not a good idea for us to stand in front of Sally and say bad things about Head Slytherin. Hermione said cautiously.

"No, it won't. Ron said, but he was not so sure in his heart, after all, Snape was really good to Slytherin students.

Sally wasn't angry, she was just trying to keep herself from telling the three of them, she was afraid that her tone would betray her mood as soon as she spoke, and she had more important things to do now.

She went to the school infirmary on the second floor and lied that a friend had been bitten by a cat, and that she was begging for some medicine like Madam Pomfrey. Despite Madam Pomfrey's repeated assertion that the injury could be healed in a second, Sally still made all sorts of excuses, and finally Madam Pomfrey angrily threw her two pills, telling her to wipe a bottle and drink it three times a day, a packet of torment to prevent infection. Then he drove her away in a rage.

Sally took two packets of pills, went to Professor Snape's office on the first basement floor, knocked a few times, and sure enough, the door opened. Professor Snape was still sitting at the table full of books, and when he saw Sally coming in, he frowned and asked, "What are you doing here?"

"I got some medicine for pet bites from Madam Pomfrey, don't worry, I have a secret, I said my friend was bitten by a cat. Sally said, holding up a bottle and a paper bag in her hand.

"It's a big deal. Snape said, "I've already taken care of my wounds." ”

"If you'd rather trust Filch's technology than Madam Pomfrey. Sally said unceremoniously, "Then you have indeed dealt with it." ”

"I think you've forgotten that I'm your professor and your dean, Sally Potter. This was the first time Snape had called Sally's full name, and Sally was a little unsure, but thinking of Snape's blood-donating calf, and thinking of what Harry had said, she decided to take a hard gamble.

"I haven't forgotten, Professor. "So I'm doing what I'm supposed to do as a Slytherin student right now, and care about us as a collective." ”

Snape and Sally looked at each other, Snape crossed countless ways of punishment in his mind, deducting points, she was a Slytherin person, punishment, light didn't have any effect, heavy enough, he couldn't do it. After a few seconds of stalemate, he sighed. "Let it go. ”

Sally didn't move as if she hadn't heard. Snape raised his voice and said, "I said, put it there." ”

"Adhere to the principle of responsibility. Sally snapped and said, "I think it's better for you to use it now." ”

"Sally Potter. Snape was really angry, he stood up, and Sally put the stuff on the table with the medicine she had smeared, and ran to the test bench with the paper bag that needed to be boiled a few steps to prevent Professor Snape from throwing her out, and she let it go.

"Is it okay to boil medicine in this pot? It doesn't look clean, but what about this?" she searched for a crucible that seemed relatively suitable for boiling medicine among the dozen or so cauldrons, trying to avoid Snape's murderous gaze. Finally, after she found a crucible and lit a fire and boiled water, Snape relented and sat back in his chair. Looking at her unskillful actions as she measured the temperature of the water, he sneered, "Judging by your performance in Potions class, I doubt that this pack of potions will be able to fully exert its efficacy. ”

Madam Pomfrey said that the packet was simply tossed in while the water was boiling and boiled until the powder was completely melted. With that, Sally threw the powder in. "I'm measuring the temperature of the water to reassure you, Professor Snape. ”

"Hmph. Snape snorted coldly. Picking up the clear bottle on the table, playing with it, and sniffing it again, he knew that it was more effective than the medicine on Filch.

"Professor Snape. Sally brought the cauldron over, but she couldn't help it, she couldn't find anything like a bowl. "You see where I put it. ”

Snape looked at the man in front of him, she had the exact same appearance as Lily in memory, but Lily had never been so worried about him, her eyes were always on the Potters, those eyes, yes, those green onyx-like eyes, had never looked at him that way.

"Professor Snape?" Sally saw that Professor Snape didn't respond, and couldn't help but scream again, which made Snape sober up, and while secretly mocking herself, she made a place on the table and said, "Put it here." ”

Sally was overjoyed, indicating that Professor Snape was going to use the medicine, and she put the cauldron on the table, explaining again that the medicine should be applied three times a day, and that she should be careful not to touch the water, and before she could finish speaking, she was thrown out by Snape by the neck.

"Cut, and don't say thank you. Sally straightened her collar, grimaced at the door, and left satisfied.

Inside, Snape had reused the medicine he had smeared, Madam Pomfrey's medicine had always been reliable, and it didn't take him a week for his leg to heal. Then he frowned at the steaming black soup on the table, his brow couldn't help but furrow and furrow, and after doing a strong ideological construction, he picked up the crucible. The crucible wasn't big, so there wasn't much medicine, and even so, Snape couldn't help but feel sick after drinking it in one go.

In his lifetime, he didn't expect to be able to drink Madam Pomfrey's potion, even if he knew that it was prepared to warn those children not to make mistakes and get hurt, it was of little practical use.
