Dexter expected another person to join them when a name was issued, but all that happened was a voice came from nowhere. The same voice that had instructed him to come to where he was now.
It was uncanny, and unnerving.
He sat because he couldn't think of anything better to do, and standing while this was figured out didn't appeal to him in any way.
Dexter was disturbed by the idea of being called to a place without the owner of that place being aware of it. Had to be the City's doing, didn't it?
"Jarvis isn't a real person?" It didn't make sense that it would be, that there was some system of cameras and microphones set up through the whole building so that somebody in a control room somewhere would be able to see and hear everything and execute commands. It was unrealistic.
