Well that was....really, really disgusting. Granted, having just been down to Tartarus, he really wasn't one to talk. But. It was still gross. But, really, if they were going to go there, he was really going to have to ask.

"How does the sea not evaporate if it's constantly boiling?"

Yup. He was totally going to make you explain this. Unless it was a misnomer and the water wasn't ....actually boiling? Or it wasn't made of water? Kind of like the river of fire?

And you know what, wearing shorts and flip flops to Tartarus was fine. It was FINE. Okay, no, it was a super bad idea but, he survived! In style!
