Nico only trained for about twenty minutes, and then he went back to Cabin 3. He wanted to make sure Percy was well and busy, which he was. Paul told the son of Hades that the heroin would hit quick, and he'd feel euphoric for 10-20 minutes; after that, he'd feel heavy and dizzy for half an hour to two hours. Nico had the perfect amount of time.

[Details of intaking the drug have been omitted. I left a couple sentences that add to character development/story, but no details about Nico actually doing the China white.]

When Nico shot it up his arm, he questioned if it would leave a scar, but figured against it.

There's no three things Nico appreciated most about the world:
The word fuck
Euphoric sex
Euphoric drugs.

Percy got off his shift early, and figured he'd surprised Nico who he knew was hiding out in his cabin. Nico had been feeling a little down lately, but hadn't said anything about it, so he figured he'd come home and cuddle his boyfriend up and kiss his beautiful face.

Nico's displaced sadness seemed to crawl right back after his hour-long venture with dope. He wasn't sure how he felt, but he was ready for a nap, or a meal, or both. He expected Percy to come later than he did, but thankfully, Nico's highs and lows were already over-with by the time Percy came by. Now, he was left just wanting some more.

He did feel a typical pang in his chest, one of guilt and loneliness, but it was easy to ignore, his mind slightly fuzzy now. When Percy entered, Nico glanced up in somewhat surprise, worrying if he looked or smelled like the H he'd just intook.

"Hey, baby," Percy walked in, already taking off his sweater and shirt. "It's hot out there. Saw you sparring, though."

Nico stayed silent but gave a subtle smile, sitting up.

"You tired?" Percy came over and placed his hand in his boyfriend's dark locks on the back of his head, kissing his forehead.

Nico leaned into the touch slightly, mumbling, "I, uh… yeah…"

Percy nodded, deciding to gently push the other boy down and lay next to him on top of the blankets. Nico sighed, leaning into Percy's chest, enjoying the cuddling. He's so warm, Nico thought. And… so am I, a bit more than usual.
