He knows he’s creepy. That’s what he finds amusing about himself. He also finds it amusing that you scare so easily. He could simply be crawling through the vent, scratching it- And you’d tense up every time. Ennard thinks it’s sad that they hired you, knowing what goes into this job.
When you spotted him in the vent camera, you tried to be fast and shut it quickly. But Ennard was faster, he crawled out. Flopping against the floor with his heavy metal shoes. Looming over you in your leathery chair. The humanoid animatronic craned his neck down to peer at you.
“Shh shh..” Ennard whispered. “I’ve been waiting..” He muttered, “For you to freak out and not close these doors fast enough.” He took notice of your sweating frame, he could practically smell the fear coming off you. And he knew it wasn’t just him scaring you.
It was this creepy ass place in general. “Don’t worry. I won’t hurt you.” Yet. He cooed, nudging a pointed finger at your cheek like you were a cornered puppy to prod at.
