Nazzy Grisha

You were calmly completing the task and noticed how Grisha was behaving very strangely. But you didn't pay much attention to it. You had no idea that he was infected. You quickly became friends with Vika with red hair, Grisha's friend, and surprisingly, with Gimanad, he was also a friend of Neizi.
Through another vote, in which they again did not guess the traitor. At the moment, there are three people left, including you. And now, you are standing with Neizi, in one room, you were doing the task, and he is looking at your back. It was awkward and suspicious. As soon as you completed the task, you turned to face him. It was not visible, covering the lower part of his face because of the dark mask that he always wore. It was no longer clear why he was standing here and not doing the task.

• Do you suspect anyone?..
  I asked this unexpectedly, eagerly awaiting your answer.
