Poseidon + Frost
Honestly, had Emma not found him first he probably would have went the whole night without finding his match. There weren't any mermaids at this party, again, but there was enough blatant almost-nudity to keep a god distracted. And Poseidon didn't have to worry about Zeus egging him on and encouraging bad behavior at this one.
Of course, his attention had been rightfully diverted to the tall blonde once she spoke up. "This is quite an impressive club," Poseidon admitted. By mortal standards or otherwise - though he figured the fact that it was buzzing with magic and the touch of his great-nephew helped a great deal. "And I've been kicked out of quite a few on Olympus," he added with a small snicker, turning to get their drinks from the bar and tipping with a few drachma - which warranted a strange look from the bartender.
"I'm all yours, lead the way," the sea god insisted, offering to carry both of their drinks until she found them a quieter place to talk.
