There were two sophomores in the back seats when Roxas climbed on the bus, and that was possibly the biggest mistake of their young lives. He tromped down the aisle with hands in his pockets, backpack on one shoulder and doom hanging around his very presence like an ominous black cloud, and paused at the second-to-last seat. He didn't do anything, or say anything, and nothing in his expression changed. He just stood, and stared, and after five seconds the sophomores scampered out of the seats and past him to find a safer location near the front.

The second to last seat on the left was Roxas's. Anyone who valued their pride and netherregions knew that. He dropped into it, back to the windows and arms on the mystery blue naugahyde backrest of the seat and the one in front of it, one leg curled under him, backpack discarded on the questionably sticky floor.

Riku climbed on exactly three minutes and forty-five seconds later--Roxas timed him, specifically so he could affect a superior smirk as Riku passed him in the aisle, en route to the last-last seat on the left. "You're late, asshole."

"Fashionably, motherfucker." Riku's backpack landed against the pressed aluminum wall beneath the window of the last-last seat before Riku himself slouched into it, slid down with his knees up against the back of Roxas's seat.

"There were sophomores in our seats, Rik," Roxas dropped the words like announcing that they'd just been exposed to a killer mutant virus and were doomed to die. "They were probably spanking it. Did you look before you sat?"

"Someone's in a mood." Riku leaned his head back, staring up at him with a sort of unruffled detachment, but Roxas noted that he shifted ever so slightly in the seat. "That time of the month again?"

"Fuck off." Roxas slid to the side involuntarily as the bus lurched to a start, doomed to circle slowly around the school once before finally exiting the parking lot. He readjusted his seating position, found a better angle from which to glare down at Riku. "Roll me a blunt."

If it were possible to see anything behind Riku's bangs, it could probably be noted that his eyebrows arched up at that. "Why?"

"Because I don't want to think about all the ways in which I just failed my math test."

Riku shrugged, reached for the front pocket of his backpack and started pulling out supplies--the special kind, in this instance, because they were all invisible. He pursed an invisible rolling paper between two fingers and started picking bits off an invisible nug out an invisible bag, still watching Roxas, perfectly practiced and coordinated. "You suck at trig."

"I don't need you to tell me that."

Riku chuckled, tamping down the invisible weed with both index fingers, and Riku chuckling had never boded well. "You suck at trig. Your life is over, you'll never graduate. You're a disappointment, Rox, a miniature, compact little disappointment with no love life, doomed to spend the rest of your days in your mother's basement."

Roxas scowled, evenly, swaying from side to side a bit as the bus picked up speed. "You finished rolling that yet, princess, or did you break a nail?"

Riku stared back, glare for glare, fingers still rolling the invisible paper back and forth until he deemed it complete, finished it off with a lick across the invisible glue line. "Fucker."

"Ooh, good comeback."

"Here." Riku twisted off the ends of the invisible joint and held it up. "Smoke this before you become any more unbearable."

Roxas hissed, plucked up the invisible contraband and pulled an invisible lighter out of his pocket, and reached over to open Riku's window. No sense in hotboxing the bus with imaginary smoke; he preferred that the driver to get him home with minimal incident.

The first hit was always the best. Roxas took a long pull, invisible joint pinched between his fingers, and held it until his lungs ached, let it out in a long, slow breath aimed haphazardly at the open window. Ah.

He was about to take another when the seat back jerked, jostling him, and Riku did that thing again where you couldn't see his eyebrows. Only this time he tossed his head just slightly to get his bangs out of his face. "You do plan on sharing that, right?"

Roxas stared at him, lifted the imaginary joint back to his lips and took a long, slow pull like he was contemplating this. He sucked air in quick, held his breath, and finally, almost reluctantly, passed the imaginary joint down to Riku.

"Thanks." Riku's voice was flat.

Roxas rolled his eyes and exhaled, settling back more comfortably against the windows. "Whatever man, it's your stash."

Riku took his hits very seriously, hunched over the blunt and inhaling at a gradual, regulated pace. When he straightened, there were two juniors across the aisle blinking at them both, looking from one to the other and then at the empty space between Riku's fingers.

Riku shrugged a little, held out the invisible joint and said, "You wanna hit?" around his held breath. When they shook their heads no he shrugged again, reached up to tap the invisible ash out the window and pass it off to Roxas again. "You forgot about your math test yet?"

"I did until you said that, fucker."
