After a moment, the door was opened by a dark-haired young man, with red-rimmed blue eyes. His face was pale, haggard with grief. "Nathan Petrelli?" he repeated, and looked at the man he recognized from their interactions over the computer.
Then he looked at the others, the man and woman, his brow furrowing lightly.
"I'm Peter," spoke up the empath. "Nathan's brother. And this is Alessa. She's a friend."
Simon nodded. "Peter. You're the one River wanted..." He trailed off, turning away and leaving the door open for them. "I have her notes, if you still need them."
Peter peeked inside the door, and immediately wished he hadn't. The size of the room within the police box hurt his brain. He gripped Nathan's arm, and let out his breath. Let's get in there, quick. Before my head shorts out from trying to understand it.
