Tony
It was the day after the frosting disaster in Tony's car and the Baby Avenger was nowhere to be found. Percy Jackson had vanished from the tower. Tony had checked and double checked every security feed in the building, he gotten JARVIS to run every possible program to figure out where and when he had left; and if it was of his own volition. He got nothing. Nada, zip, kaput. Nothing.
"Where is he?!"
Natasha was, surprisingly, the most panicked. Tony never would have guessed that the cold assassin would have developed such a soft spot for the newest member of their team so quickly. Bruce was pacing in his special room, clenching and unclenching his fists as threads of green appeared and disappeared all over his skin. Clint was desperately trying to convince Thor to go to Olympus to ask the Greek gods and getting nowhere.
"You have too! What if he is in danger!" The Hawk yelled, face growing redder by the moment.
"I cannot. It goes against the ancient laws. To break such a thing-" the asgardian shuddered. He looked thoughtful for a moment before growing serious. "Besides, to be a child of Olympus, especially the son of the sea god means he is always in danger. Percy will contact us if he is in need of assistance." Tony looked up from his computer where he was currently hacking every camera in the state of New York. He growled at the Norse god.
"He doesn't even have a phone. How the hell will he contact us?" It was a show of how worried everyone was that Steve didn't get on Tony's ass about his language.
"Stark! Language."
Never mind.
The elevator doors dinged and swung open as Tony turned to glare at the first Avenger.
"Steve now is not the time to..." Tony started to snarl. He cut himself off abruptly when he saw a pale but bemused looking Percy stumble out of the elevator, closely followed by his scary cousin Nico. The older teen looked around the panicked chaos of the team in crisis, his eyebrows rising on his face.
"Hey guys, whats up?"
