Robin walked into the living room, and immediately froze at the sight he was seeing. Robin was terrified. He wasn't sure if he was seeing things, or if it was actually there. There was a boy standing in the back of the room. Black hair fell in front of the boy's face, covering his eyes. Robin was frozen in fear. The boy didn't seem to be looking at him. He was facing forward, towards the wall, seeming to be looking out the window. Robin didn't dare move. The boy was wearing a black hoodie, and he held a book in his hand. He was just standing there, immobile. Robin wondered if the boy was alive. There was no sense of movement whatsoever. Robin blinked. The boy had disappeared.
He shook his head. "I must be seeing things," He thought. "I need to get more rest."
The Titan then climbed up on the couch, trying to process what he had just seen. He was completely confused, lost. Then, Beast Boy and Cyborg walked in, laughing. It seemed that the rest of the Titans had woken up. Raven teleported in, looking miserable and depressed as usual. Everyone seemed to be their normal selves, except Robin. The rest of the Titans didn't notice, but it was clearly noticeable in Robin's actions that something was wrong.
To collect himself, Robin decided to walk around Jump City while the others goofed off, like they normally do.
To Robin, something seemed…different. There weren't this many people here before, were there?
There seemed to be a lot of people now, and the ones that seemed out of place were all wearing something obscure. However, none of the strange newcomers even seemed to notice the other people. In fact, it's almost like the people he saw didn't even exist, like they were in their own world. Like there was no one there.
"That's it. I need to talk to Raven." Robin thought.
And with that, he took off running.
Not one of those people looked.
