Wizet noticed something: although the figure was Voldemort, Dumbledore was not watching him. Instead, he was gazing into the distance.
The place Dumbledore was looking toward should have been Hogsmeade Village.
Earlier, when Wizet transformed into an Obscurus and rushed toward the location of the Dark Mark, he had noticed Flitwick, Sprout, Alastor Moody, and McGonagall running toward the Quidditch Pitch.
The purpose of the four professors was not difficult to guess—they were heading to the Quidditch Pitch to guide the students and organize them into returning to their respective houses.
This should have been handled personally by the Heads of House. Since Snape was absent, Alastor Moody's presence in the group clearly meant that he was taking on the duties of Slytherin's Head of House, responsible for organizing the Slytherin students.
The reason for Snape's absence was also easy to guess. Naturally, it was because of the Dark Mark suspended high in the night sky.
From Fenrir Greyback's memories, Wizet knew that Snape had once been a Death Eater.
As a Death Eater, Snape had clearly been branded with the Dark Mark by Voldemort, just like Lucius Malfoy.
Both to avoid suspicion and to prevent unnecessary trouble, leaving Hogwarts was undoubtedly a good choice.
That made Snape's whereabouts easy to determine as well. He should have gone to Hogsmeade Village and hidden in the Shrieking Shack.

"Oh?" Dumbledore responded with some surprise. "Did you see Minerva and the others on your way here?"
"Mm..." Wizet admitted. "Professor Snape
