Duke knew you were there, at the manor. He could sometimes see you run around a corner or down the hallway.

Albeit, he could never see you directly, you seemed like a shy ghost. But he knew you were there, you made plenty of noise when you wanted someone's attention.

The first he remembered seeing of you was when Bruce brought home an old clock, apparently a friend gave it to him after he offered to take the broken clock.

Not even a week after the clock arrived you made your presence known, turning on sinks and running around the manor at night. From what Duke could tell, you weren't malicious or anything, just a bit curious. And maybe a little mischievous.

He knew the others noticed you, but Bruce hadn't called Constantine yet so nobody made a fuss. If you weren't doing anything to hurt them why call for help?

Today you were much more active than usual, Duke had seen you watching him from the doorway. But what he didn't expect was to hear a giggle from behind him while he was training, he whirled around quickly, startled and shocked.

There wasn't anything there, at least at first glance, but he could see you peaking out from behind the bat computer.
