Oh, now, that wouldn't do. She had already stripped Tony of some of his armor, he wasn't about to just start talking about himself for nothing. He gave her a slow, impish grin, like he was waiting for her to realize some mistake she had made in opening that particular door, and when she didn't close it fast enough he answered, "Whatever kind makes your heart beat, sweetheart."

Maybe their worlds weren't as different and she made them sound, and, hey, they both liked music. Presumably. Twinkle Twinkle couldn't have been the only thing that transcended the barrier between Earths. Tony tipped carefully closer to nudge her shoulder with his own in encouragement and tried in a low, lilting purr, "I'd sell my soul, for you, babe..For money to burn, for you.." He watched closely for any sign of recognition as he sang, giddily ready to jump to his feet and belt if she was on board.
