Natasha was right. It was easy. But Bruce felt terribly guilty as the kid crumpled to the sidewalk. Steve swooped in and caught him on his way down, making sure the kid didn't hit his head.

"Perseus Jackson is in custody." Nat said into her earpiece. Tony's voice came back through the speaker.
"Bring him back to the tower. Fury wants us to interrogate him." Bruce tried to remind himself that the kid was a suspected terrorist; after all he had blown up several schools and a bus. Among other things. But he still couldn't shake the feeling that they'd bitten off more than they could chew.
