That's right! Sirius was searching for none other than Snape.
To be honest, when Snape suddenly revealed his hiding place in the alley opposite the apartment building when he first arrived in this community, he really didn't think about anything else.
After all, those who were across the street at that time were Professor McGonagall and Snape, and at most the two Hogwarts girls who had just left were included. Even though he had always disliked Snape, now he didn't We have to admit that the other party is also "one of our own".
Therefore, he did not hide his existence excessively at that time, and it did not seem to be too unexpected that Snape was so keenly aware of his appearance.
Because of this, after being pointed out by Snape, he simply went out and met the two of them directly, and even took the initiative to mock Snape about the matter.
In fact, Sirius didn't even pay much attention to Snape's sudden departure when talking to McGonagall not long ago. Because he also knew that on the basis of his displeasure with the other party, the other party had actually always hated him. There didn't seem to be many unnatural signs in the guy's early departure.
Of course, among the factors that prevented Sirius from noticing something was wrong from the beginning, the most fundamental reason ultimately lies in one point - Snape's Occlumency has actually been practiced to a quite deep level. It is so difficult to find any flaws in a person.
However, when Colin fainted suddenly, Sirius followed McGonagall to the temporary ward and saw the pictures of Colin left in the magic film. He finally indirectly discovered something was wrong!
Although the film picture of the suspect was blurry, he could almost confirm that he recognized the scene in the picture!
Isn't that the next door to the alley where Snape revealed his whereabouts? Go into the alley next to it and walk to the other end, where the film scene is, and opposite it seems to be the temporary student dormitory where Colin was when he fainted.
He passed by there when he came!
Thinking of this, the specific scene that he had initially overlooked when Snape reached out to point out where he was gradually became clear again in Sirius's mind. He gradually began to realize that although Snape was indeed referring to him at that time, the other person's eyes seemed to have glanced past him inadvertently.
Yes, although the memory is still a bit blurry... after all, it was something that I had ignored at the time. Even if I noticed something strange afterwards, it would be difficult to reproduce too many details in my mind one by one. This was the time when he was silent in the ward not long ago.
However, even if he is not completely sure, Sirius's practicalism and high mobility do not prevent him from following these few points and starting to use practical actions to verify his guesses.
And after he "verified" it after leaving the temporary ward, and using his best tracking ability to search silently, he finally found this place by following Snape's traces.
He was very sure that Snape must be in the old apartment next to him, because the reaction of the curse was actually heard in this old building that seemed to have been abandoned for a long time!
Until then, Sirius, who was squatting under the window sill and slowly lowered his wrist, had gradually raised the corners of his mouth.
"That guy... what is he talking to people about inside? And it seems that the origins of those sneaky guys may not be that simple."
While he was thinking about this, Sirius, who was still considering how to take a peek without disturbing the people inside, suddenly raised his eyebrows, as if he suddenly noticed something.
"Um?"
He suddenly discovered that the reaction to the magic spell on the other side of the wall began to weaken rapidly, and then completely disappeared. And then, there was a sound of very regular footsteps.
"Squeak-"
There was a sound that was probably a door opening, and the footsteps gradually faded away, leaving the room that was only separated from him by a wall.
"...Are you a little late?"
That was probably Snape's footsteps - a long stride, as if he was always in such a hurry. Just listening to this sound, Sirius could quickly outline in his mind the lightly fluttering cloak. The "Big Bat" image is coming.
"Well, he should be planning to leave through the main entrance on the other side." He thought secretly in his mind, "However, those infiltrators should not have moved yet."
The curse, which was probably a silencing spell, had been lifted, but after the footsteps faded away, there was still no sound in the room. Considering that unless those people are ghosts or dementors or something, and they don't walk on their feet at all, there can only be one reason - those people still don't feel how safe it is here, so Snape After leaving, he still maintained a high degree of vigilance.
Squinting his eyes for a moment, Sirius wisely chose not to alert the enemy immediately based on his experience, but instead retreated in the same direction while remaining quiet.
Some of his previous conjectures had been verified, and he could contact Professor McGonagall. So we need to stay a little away from here, so as not to let the few infiltrators who are probably hiding there notice the movement.
But just as he quietly retreated to the entrance of the alley and was about to go out, Sirius suddenly stopped and stopped suddenly.
"You think I'm right? Huh, it's really a dog's nose... and it's not a nose that ordinary dogs can have. Even deodorizers don't work."
When he heard these words coming to his ears slightly but clearly from the wall outside the alley, Sirius narrowed his eyes again and lowered his voice and asked:
"Why, I caught you sneaking here to 'chat' with someone behind Professor McGonagall's back. Aren't you at all panicked?"
As soon as he finished speaking, a figure outside suddenly took a step from the side and stepped into Sirius' line of sight.
Sure enough it was him! Severus Snape.
"I'm just taking care of some personal matters first... I've already taken care of it, and you can do whatever you want to do next—if you want to take this matter to Professor McGonagall later, it's up to you. As for now... don't bother me. Me! Unless you want to lure those inside out now."
After saying these words softly and pointing in the distance, Snape decisively turned around and walked silently away. Sirius probably didn't expect this guy to be so calm, so he was stunned for a moment, but in the end he didn't deliberately pursue him.
"'Private affairs'? What?" He frowned and thought to himself.
