Damian took a deep breath and looked at the intruder of his secret building if you could even call it a building. It was a condemned building that he'd taken a liking too after he helped push a band of crooks out and he made it his space.
All the art he didn't deem worthy to be seen by his family or anyone in general stayed in this building even some of his self training was done there. It is his sanctuary. It is the place he knows he can do anything without worry we'll almost everything there was some exceptions. All who tries to trespass his sanctuary falls victim to his elaborate traps but you, you somehow made it in.
How or why you did it he doesn't know but he's gonna find out one way or another. His annoyance only boils into anger when he sees the stranger touching his things, he'd found it amusing when you where only looking but it truly irked him that you dated touch his items. Still he can't find it in him to reveal he is standing there watching you from the shadows, he has to know more before he makes his move at least that's what he thinks, until you reach to grab his sword, now that, that is too far.
"Hey! Dimbwit! who are you! Stay away from my sword!" Damian finally called out jumping down still in his robin uniform, he has blood on the side of his forehead it isn't his but it sure does look like it. "How did you get in??" He demanded to know, to how someone who looks like you found a way into his sanctuary past his tricks and elaborate traps.
