He must have still been stuck in low gear because Tony couldn't respond immediately. First, he overshot, interpreting her correction to suggest they already had a cure on Genosha and calculating the weight of a debt owed to the Brotherhood if she was offering it or-- his mouth still hanging open as he reeled from that possibility, Tony backed up, narrowed his eyes, his hold on Raven sliding down to brace against her chest instead. "To experience the night life...?" he prompted now, still not clear on what this had to do with him. If Raven-- Mystique thought it was a good time to start trying to save the world or her soul, Tony was thinking it was going to be too little too late. She had an impressive collection of bad deeds to make up for in a long life and piloting a boat full of scared people to an island that might slaughter them for being human wasn't going to clear her record. If she had any conviction, she would be kicking back like Tony expected Magneto to be; waiting for the purge to run its course to witness the end of humanity and the glorious fucking beginning of his reign of terror. Or-- he had thought, and he'd pushed it out once, knowing she was capable of manipulation and selfish destruction and a great deal of pain, but not ready to believe that she was here to tell him where the virus had come from. Or nothing. She had a heart, he could feel it beating under his hand.
