In the quiet, dimly lit classroom of Naucalpan, a mysterious verification video begins. A hooded figure, believed to be the professor, stands before a locked door, his face obscured by shadows. He speaks in hushed tones, "Today, we verify." The camera pans to a desk, where a single, unmarked envelope lies. The professor approaches, his footsteps echoing in the empty room. He opens the envelope, revealing a small, metallic object. The camera zooms in as he places it on the desk, reflecting the dim light. The video ends abruptly, leaving the viewer with more questions than answers.
