Kate and Tony [multiples welcome!]
Tony had shifted into his armor the moment trouble started, and while the fact that his entire suit was housed inside of him was a bit ouch, it still worked way better than trying to downsize and cram it into a necklace or carry around a mobile armory.
A long metal shield and some anchoring devices plonked down into the stone floor, and Tony looked down at Kate from where he was crouched over her, keeping her from being sucked in. .
"Hey, Kate!" he said, rather cheerfully. "Fancy meeting you here during the universe's greatest party foul. You ok?"
