Alyssa had completed her hacking and the scene of her entering the infirmary was playing. Both the principal and the attendant can see that she hadn't touched anything after entering the room.
Just then they heard a knock coming from the principal's office door. They saw a young freshly appointed doctor entering from it. The doctor scanned the scene. He saw Alyssa sitting in front of the principal's computer and he can see on the computer the CCTV footage of the infirmary. He looked to the principal's and the attendant's foul expressions. He felt confused. He was standing by the door not knowing what to do. Just then he heard the principal saying, "Come In". He entered the room and politely closed the door after him.
Mr. Linton said, "Check this girl's would and tell me whether she had applied any medicine on it or not."
The doctor was confused. He wanted to shout and say, 'Can't you see in the footage that she hadn't applied any medicine on her wounds'.
