Poseidon + Frost
Emma had spent a portion of time among the Atlaneans, with Namor. They weren't mermaids in the strictest of senses, but they were fish-people for the most part. She could, obviously, understand the appeal. Although he was clearly still good with the flattery.
"Never say never, maybe you'll be fighting for space in your water kingdom in the middle of a desert soon." Hard to say who had control over these things; maybe an influx of mermaids was just around the corner. Emma wasn't going to contemplate what that might lead to in the lake.
"Tonight is all about having fun though," because of course it was. Emma lived a truly hedonistic lifestyle, it had taken something of a backseat to the fight for mutant rights, but that didn't change that she'd put on a decidedly clingy dress with a plunging neckline. "I'm certain I can be suitably entertaining, even if I'm not a mermaid." A snap of her fingers could have men fawn over her, but Emma was prepared to play it a little more subtle, dropping her hand to Poseidon's thigh while scooting closer. "I'm sure there's more than just mermaids swimming in that head of yours."
