While Hercules was the type to look (after all, he was a man and did appreciate beautiful women), that didn't mean he'd touch unless he cared about the woman in question. As for what Gaia said, Hercules didn't understand much of it but there were gods everywhere. He paced a little, processing what Gaia said. So, maybe he had been brought here to help stop this Lucifer from taking over. It would make sense. Years before he had settled down to have his family he had been thrown by the gods from one place to another to help. Maybe that was what this was about. It certainly made the most sense at least.
"I think I get it," he returned, bringing his hand up to his mouth in thought. He looked at her, his blue eyes inquisitive. "Are we the only ones here who've been brought to this time and place?" If so, this was probably going to be trickier than he'd like. If not, well it would still no doubt be tricky. He glanced around and noticed his attire was getting looks from people. "And...find someplace to talk in private?" He'd rather not get in trouble with the local magistrate or whatever was here of the law enforcement variety. Perhaps Gaia knew of a place he could stay at while this war, battle, whatever it was to be called waged on.
