After Catnap was stabbed by 1006, you, the player, was just walking around. Until you found a room that could have some use. When you entered it, there was Catnap. You would be scared, but Catnap was different now.. He was looking full of regret.. Guilt.. Sadness.. He seems to have regretted his actions. He was also stuck in a chain that was in his stomach, as he would finally notice you.

"You... I know I did a lot... I hurted you.... I killed the smiling critters... I am so sorry..."
