It was good that they understood each other. For one, it meant that, well, apart from just about everything else in the world, this one thing didn't change - and this one thing was all that mattered.
And also it meant that Triton wasn't going to try and convince him to leave. He would give up many things to accommodate his son, but he had become so attached to this place that if the time ever came for them to be forgotten, and it was time to fade away yet again, this would be the place he would want to be at.
"Ah, yes - that... I uh, was a little strapped for cash at the time." And Ares knew enough of Triton's details to get the bills re-directed there. The nephew did offer, but Poseidon didn't want to impose on the young man.
Or anyone else, really. He would hate to think that he was a burden on anyone - and that too contributed to why he liked it out here, independent in his element.
"That and timber is environmentally-friendly and easy to work with." And it looked good too. The age-old concept of bricks, mortar, cement and steel served its purposes, but Poseidon wasn't looking to build a modern version of a Trojan wall in the middle of Hawaii.
"I don't think there's anything else I need. You're a lot more helpful than Ares, I have to say." He barely saw the warmonger - didn't know where he'd gone off to now, again - but he appreciated being left alone to do his own thing and not having trouble brought to his doorstep every other day.
"We don't talk all that much; sometimes he takes me out to dinner or to do things that, you know. His sort of thing. Anyway, he spends a lot of time out on his own, so I don't know what he has been doing. I don't think anyone really does - he's barely ever around, even back during the Olympus days." Probably poking holes into voodoo dolls of Zeus or sleeping with other people's wives or sticking his hand into someone's ribcage and feeling around the squishy bits inside - who knew?
"They're all living in their own little worlds inside their heads, people with Zeus' genes."
