Part 2/2, complete.
Colin: They locked me in a cage for almost 1 month, we still don’t know the cause of this strange virus. It might return…I’m scared.
The reason why Tony’s eyes are hidden is because Colin can’t remember everything about that day (the virus can infect the computer’s memory). He can’t remember everything, but he knew what kind of expression Sketch would have, but he didn’t want to know Tony’s expression. He’s afraid that Tony would see him as a monster.
