He nodded to acknowledge each of their greetings. When the kid sat down, Will stared at him for a few seconds, trying to suss him out. He couldn't have been more than what, twelve? If that. But the kid seemed to know exactly why he was there, and when he took out the laptop, Will grinned to himself. Looked like he was a smart kid.
The rest of the group came in a steady flow- introducing themselves to the present group as they arrived. Nobody really stood out to him- two of them, a man and a woman looked somewhat tired. The other girl had a face that he knew he could read if he wanted to. When nobody else had turned up for a while and nobody had still said anything, Will took it upon himself to speak. After all, it had kinda been his idea to put it out on the radio. Not that it had been his idea in the first place- word had been travelling around about people who wanted to do this, so he'd decided to just... Go for it.
"Okay, so, seeing as nobody else is taking charge, I will. We should probably introduce ourselves first- I know all of your names, but nobody knows mine. So, I'm Will Sykes, and I have the ability to screw with people's heads in that I can create a blast that can cause confusion, headaches, nausea, or unconsciousness. I have a theory that I could also potentially cause death but don't want to go that far." He shrugged a little.
