Steve
Steve didn't know what to make of Perseus Jackson. The kid was different.
When the teen had woken up handcuffed in an interrogation room he had been completely calm. The kid just quietly unlocked the handcuffs he was in, surprising Steve. He'd been shocked when the kid had then proceeded to lock them back onto his wrists and repeat the process again. And again. He hadn't flinched under Natasha's glare and had answered every question, but most of the answers were near useless. The only reaction she'd really gotten out of him was in the beginning when he'd flinched out of the blue before answering the first question about his name.
Nat walked back into the observation room. Perseus, or Percy as he'd introduced himself, was leaning back in his chair now looking bored. Just an ordinary teenager. Except he was too calm. Too collected. And Steve knew that he'd caught a glimpse of something in the cemetery the night before; something dangerous. Something terribly sad and broken. Whoever the kid had felt obligated to visit at three o'clock in the morning had mattered to him, and mattered a lot.
"I'll go in next." Steve offered when Natasha walked into the observation room where the rest of the Avengers were observing. Natasha shrugged, a silent acceptance of his request. He picked up an unopened water bottle before heading to the interrogation room. When he opened to door to the interrogation room the kid barely blinked.
"Can I ask a question?" Percy abruptly asked. Before Steve could even nod he plowed on. 'Who are you people? What do you want with me?" His tone matched Steve's when he demanded to know what Tony was thinking after he did something stupid. A tone that said he wouldn't accept anything but the truth. Nothing but the full truth. Then Steve registered the question.
"I'm Steve Rogers. Captain America, of the Avengers." Steve said cautiously. He thought back to when they had first met the kid just that morning. He hadn't recognized them then either.
"Sorry, but the who?" Percy asked, sitting up straight, his expression completely bewildered. He clearly had no clue who they were. Steve wasn't sure how to respond to that.
"The Avengers. Earth's mightiest heroes, we saved the planet from an invasion a few months ago?" Steve elaborated slowly, still shocked. He never considered himself particularly egotistical, but the Battle of New York was a big deal. It had been broadcast all around the world. Percy shrugged.
"I've had a busy year." His expression was fairly neutral, but something in his eyes hardened, grew colder. Steve blinked even as he passed Percy the water bottle. Steve leaned back, folding his arms across his broad chest watching the teenager chug the water back.
"Doing what? It was all over the news." Percy swallowed the last of the water. Wiping his mouth the bottle crumpled slightly under his tightening fist as he answered.
"Family drama; wasn't really paying attention to outside news." He said vaguely. Steve sighed.
"Look kid," Percy interrupted
"Don't call me that." Steve plowed on.
"... I can't help you until you start answering questions. Your record is impressively clean considering how often you are sighted near various, ah, accidents." Steve says slowly. The water bottle crunched under the kid's fist, Percy's eyes flashing.
"What do you want." He asked shortly. Steve sat up as Percy's whole demeanor changed. The kid looked angry and dangerous. A predator. And he didn't say anything about his innocence. Something is up with the kid then.
"Nothing, we just want a few answers." Percy frowned.
"You don't need to kidnap someone to ask these kinds of questions. No matter what your files may say. You want something else." The kid was smarter than he looked. Steve looked at the mirror. He didn't need to see through the glass to know what they were going to do next. He stood up.
"Follow me."
