Restlessly fidgeting with the flask cap again, Tony was slow to reply. It was only when he tore his attention away from it and twisted his neck to take in Billy that he actually started to think about it, and really he was thinking more about that cough and the strain in Billy's voice, and how much longer they might be down there.
"Make a public apology," he said flatly, and filled the time he took to push himself up onto his knees explaining, "Take out ads, you know, 'I'm sorry I deflowered your daughters, this message is endorsed by Tony Stark'." He left Nick's flask where he had been sitting when he shuffled closer to Billy, but didn't get very far. He just sat back with one knee pulled to his chest, facing Billy with a question he hadn't quite formed on his face. He'd held up well in India, but three lives pretty well depended on Billy exerting who knew what kind of energy to keep this shield up for who knew how long. Wanda had been made comatose for days after some spells, and she had more experience and was quite healthy during both incidences. Now was not the time to be passing out.
