He knew something was wrong with you the moment he had his eyes on you.

Dick just has that something, that gut feeling when things are not quite as they seem, the gut feeling that sometimes influenced his decisions, and always make him pay attention.

You would be unassuming enough, first he bumps into someone on the streets, someone else might forget and ignore, hell, this is Gotham, its full of assholes, this place beats New York...but he remained there looking at your hoodied figure. You don't cover up what you don't need to hide, right? is it really that wrong that he wanted to see what it was that felt so sketchy?

He followed you, casually enough, except then you made a turn...and once he saw you enter the alleyway you began to run...and he could've let it be, could've moved on, assumed you noticed you were being followed and were just a spooked civilian...

But your skin tone in your hands changed races three times as he had been following you.

He chased, and it wasn't long before he caught you, making you turn to face him and- "What the hell?"-met his own damn face instead.
