I wasn't going to post unless someone genuinely wanted to read it, so thanks to you guys who PM'd me. :)

Yeah, I think is going to be a multi-chapter, but I should be able to complete it quickly.

Last thing: This is set kind of AU-ish, because I have no idea where in the series this kind of circumstance would fit in. Whatever. :P

Disclaimer: I don't own Death, the Underworld (why would I want to? Property taxes, HELLO!) or PJO.

Chapter 1

Why Lord Hades had ever made Thanatos baby-sit his son was completely unbeknownst to him.

After all, Thanatos was Death. Most people didn't trust their kids to Death. Probably because they didn't want their kids to end up Dead.

Apparently, Lord Hades was not most people. And his son, Nico di Angelo, was definitely not most kids.

Oh, no. Nico was highly annoying and energetic, AND he wasn't scared of Thanatos at all. In fact, he wanted to know about everything he did.

"What's that thing for?"

"Is your job fun?"

"How come you have wings?"

"Dude, your house reeks. It smells like dead bodies and old ghosts."

"Does your brother [Hypnos] do anything besides sleep?"

Thanatos gritted his teeth. The kid asked so many questions, and consecutively too, so that he had a hard time keeping track of what to answer.

"Reaping souls, yes, I don't know, that's not a question, and no, not usually."

"Fine, I'll rephrase it as a question. Why does your house smell like dead bodies and old ghosts?"

"I live in the Underworld. With lots of dead bodies and old ghosts."

"Oh." Nico thought about that for a moment. "But Hades' palace doesn't smell bad."

"That's cause his wife leaves her pomegranates and whatnot everywhere and masks the smell of death and rotting with fruit." Thanatos rolled his eyes.

"Hmm. So that's why it smells so weird. I always thought that was just some kind of new Underworld cologne."

"NOBODY IN THE UNDERWORLD WEARS COLOGNE!" Thanatos exploded. He couldn't help it. He had a long patience, but this kid was wearing it thin.

"Hey, if I poke Hypnos, will he wake up?"

"No." Thanatos suddenly had an idea. "You have to wake him up like this."

He put his mouth right next to the sleeping god's ear and yelled, "PIZZA DELIVERY'S HERE!"

Hypnos jolted up and knocked the side of his head into Thanatos' face. "Coming!"

Nico cracked up.

Thanatos said, "Hey, while you're awake, do you have any idea what to do with Hades' kid?"

"Hades has a kid? Who in their right mind would… okay, never mind." Hypnos looked about nervously; the gods were always listening.

"He's driving me nuts," Thanatos groaned. "What should I do?"

"Give him this." Hypnos pulled a glowing purple amulet from around his neck.

"Great. Jewelry. Of course twelve-year-old boys love jewelry. Why didn't I think of that?" Death muttered sarcastically.

"No, fool!" Hypnos sighed dramatically. "It's the amulet that allows me to travel into other people's dreams!"

"Are you sure it's a good idea to let a kid have that kind of power?"

"Sure I'm sure. Now good night." The god of sleep promptly curled up and went back to sleep.

Thanatos eyed the amulet warily before handing it to the still-laughing Nico.

"Here. This necklace will give you the magical power to travel in other people's dreams. Now shut up and leave me alone. I want to go watch Deadliest Warrior."

With that, the god of death walked over to his recliner and flipped channels, searching for his favorite show.

"BLAST IT! It's samurai versus gladiator again!"

Nico scrutinized the glowing purple amulet. Then he shrugged and slipped it around his neck.

There was a flash of bright violet light, and suddenly the son of Hades was asleep on the floor, the amulet still around his neck.

Thanatos vaguely wondered if he should do something, but he figured that of course his brother's amulet made the wearer fall asleep. He wore it all the time and was always asleep.

He's the lord of the Underworld's son. Ah, he'll be fine.

So. Who should Nico prank first?
