Robin was so angry at Slade that he didn't even see what he ran into, or who he ran into.

He'd half expected to see him standing there, he had a habit of appearing out of nowhere, and as far as Robin knew, he was the only other person here. But it wasn't Slade who they had literally bumped into, in fact they didn't even know who this person was.

Clearly the other had been knocked back by their collision as well, but unlike Robin, he'd somehow managed to catch himself on the wall to stop himself from falling.

The boy looked a little bit younger than the spikey haired hero. Soft curly blond hair had fallen in front of their face, obscuring his eyes, he was a little shorter, and slimmer built than Robin. The plain clothes he was wearing didn't look like he had been training, or going on missions like him: a white short sleeved T-shirt and light blue denim jeans, both clean but very slightly splattered with paint.

Once he got his breath back the blond smiled sheepishly and offered his hand to help the confused titan stand up, using his other hand to push back his hair and reveal big bright sea-green eyes. He didn't know why, but Robin could sense that the boy was different somehow, and he definitely didn't seem like he fit in with the dark gloomy clock tower Slade was keeping them in.

As soon as Robin found his feet the boy raised a hand into a fist and rubbed his chest. Robin didn't really understand what he was doing, maybe he'd hurt his chest in their collision? But the look on his face showed that both of them were just as surprised to see another person here.

"Joseph!" Slade's cold voice was unmistakable from the other side of the clock tower, stern, and leaving no room for arguments as usual.

The other boy's head quickly snapped to the direction of the mercenary's voice. Giving an apologetic smile before hurrying off down the corridor, Robin knew from experience that it wasn't a good idea to keep Slade waiting.

But who was this boy? Was Robin not the only person Slade had blackmailed into working for him. It was hard to believe anyone would be here willingly. But he'd never seen him before, he wasn't any hero or villain that he was aware of, so why did Slade have him here? He seemed too gentle and kind for Slade to have any interest in, Robin knew better than to assume a person after just meeting them, he couldn't explain why, but he felt like he wanted to trust that boy.
