Chapter 10
Variable Shift
Austen
Luke’s phone chimed again—third time in ten minutes—and his jaw twitched like the muscle didn’t know whether to lock or sprint.
We sat at opposite ends of the dorm, him on his bed lacing up running shoes for weights, me at the desk debugging a freshman’s horrendous MATLAB loop.
From the angle of the screen, I couldn’t read the alert, but whatever it said chased the color from his face.
He shoved the phone under his thigh, yanked the knot tight, and tried for casual. “Back by eight,” he said.
“Mm-hmm.” I kept eyes on my monitor, fingers still on the trackpad. The cursor blinked inside an if-statement I’d already fixed. “Have fun pushing iron.”
He grunted acknowledgment, grabbed his backpack, then paused. “Need anything from North Point?”
“Blueberry oat bar. If civilization collapses, I’m building a fort out of them.”
The smile he gave was automatic, not lived in. “One fort, coming up.”
Door shut. Hallway swallowed his footsteps. The radiator hissed an exhale that sounded like “don’t buy it.”
I minimized the code window and opened a blank note.
VARIABLE: Luke OBSERVED DATA – Phone buzz x3 in 10 min – Pulse spike visible at temple – Left shoe double-knotted (stress habit) – Smile latency 0.5 s (not baseline)
Hypothesis wrote itself: something academic, probably ugly. Athletes didn’t bother double-knotting for girlfriend drama.
Problem: No proof. Also, none of my business.
I closed the laptop before the note turned into a rescue plan, shoved it in my bag, and headed to Ridgeway. Numbers were safer when they belonged to other people.
The math lounge smelled like old carpet and burned Keurig pods.
A cluster of sophomores argued over divergent series at the whiteboard.
I claimed the far table, noise-canceling earbuds in, and attacked stack two of tomorrow’s quizzes.
Twenty minutes and a dozen chain-rule misfires later, the door cracked.
“Austen,” Maya sing-songed, sliding into the chair opposite me. Red beanie, fingerless gloves, eyes that missed nothing. “I have not seen you in the cafeteria in days, so I’m conducting a wellness check.”
“Luke keeps bringing me nutrition bars, so I’m good.”
Maya rolled her eyes. “You realize those are snacks and not meals? They’re to tide you over until you eat actual food?”
“I know,” I snapped.
“So, you’re in a mood.” She unzipped her coat. “Lay it on me.”
“Nothing to lay.” I flipped a quiz, red-penned a circled integral. “Roommate’s busy, radiator at equilibrium, calculus kids mostly remembered their limits. Banner day.”
She hummed. “Banner days don’t make you talk in bullet points.”
I kept pen moving. “Luke’s phone had a small meltdown. That’s all.”
“Define meltdown.”
“Trio of notifications, visible spike in heart rate, possible extra shoelace knot.”
“Academic?”
“Statistically probable. I am tutoring him later in financial accounting.” I dated the quiz margin, slid it aside. “Didn’t ask.”
“What do you know about financial accounting?”
“Nothing,” I admitted. “But math is math. I can follow a formula with the best of them.”
“So, what was wrong with Luke?”
“Didn’t ask.”
Maya leaned back until the chair squeaked. “Because asking would violate… what, subsection four of the Roommate Neutrality Pact?”
“Because he didn’t offer.” I lined up the next quiz square with the edge of the desk. “Data without consent is surveillance.”
She snorted. “You’re already surveilling; you want permission to analyze.”
“Not the same.”
“Sure.” She stood, snagging my pen mid-stroke. “Break. Harbor Commons. You can buy me bubble tea with all the moral high ground you’re saving up.”
I opened my mouth to argue—saw the sophomore herd prepping to stampede my table—and closed the gradebook.
“Fine.”
Harbor Commons never decided what it wanted to be—half café, half airport terminal, acoustics for neither.
We wove through clusters of students and found two seats at the window bar.
Outside, dusk bled pink across piles of plowed snow; inside, someone’s Bluetooth speaker fought the house playlist and lost.
I ordered black tea, no tapioca; Maya went full unicorn—lavender milk, rainbow jellies, 150 percent sweetness. She watched me tap the debit pad.
“Want to talk now or after your annual sugar panic?”
“Now’s good.” I popped the lid on my drink, steam fogging my glasses. “Luke looks like he swallowed a hockey puck.”
“Practice injury?”
“Phone injury.” I told her the observable facts, stripped of speculation. She sipped purple sugar sludge and nodded like a clinician.
“What’s your move?”
“Wait for him to say something.”
Maya raised a brow. “And what if he doesn’t?”
“Then I continue not violating room-rule confidentiality.”
“You mean the rule only you follow.”
I took a measured drink. “He’s entitled to privacy.”
“He’s entitled to help, too.”
I traced the moisture on the cup with a thumb. The condensation smear looked like a goal crease—semi-circle, chalky. “I am helping him, with math.”
“You’ve got the academic recovery plan,” Maya said, blowing on the steam rising from her cup. “But do you have the human plan?”
“Define human plan.”
“Actually talking to him,” she said. “You treat him like a broken equation. Maybe try treating him like a roommate. You know, ask a question that doesn’t have a numerical answer.”
Point, Chen.
I stared into the dark swirl of my black tea. I thought about earlier—Luke staring at his phone, the way his jaw had locked tight. I didn’t know the sender, but I knew the reaction. It wasn’t an academic failure; it was a personal one.
Risk assessment: Asking about his life might blur lines, but so did letting his problems become my problems. And they already were, whether I admitted it or not—the room felt off-balance when he left it unsettled.
Maya nudged my ankle with hers. “Your face is doing that linear-programming thing.”
“Meaning?”
“Optimizing a solution while pretending it’s hypothetical.”
I cleared my throat. “He has weights until six. If he circles back before team film, I intend to… expand the inquiry parameters.”
“In English?”
“I will ask him how he is. Qualitatively.”
“Revolutionary.” She poked a crumpled sugar packet at my forehead. “Proud of you, nerd.”
I salvaged dignity by flicking the packet into the trash on the first try—two-point shot. The playful clap she gave echoed louder than I liked; heads turned, but no one cared.
Time check: 5:37 p.m. Enough to grade a few more quizzes, not enough to obsess.
“I should get these done,” I said. Standing up and getting ready to head back Ridgeway. “You volunteering to double-check partial credits?”
“Tempting, but I have feminist lit at six.” She picked up her bag. “Text me once you solve for x.”
“x equals maybe.”
“x equals yes,” she called over her shoulder, disappearing into the quad.
I walked back alone now—tea cooling, and a variable I was done pretending to ignore.
Back at Ridgeway, I graded with the efficiency of a tax accountant on April fourteenth. Red pen flew. Exemplary answers got smiley slashes; sloppy ones, terse arrows. When the stack shrank to zero, my phone read 8:42.
I stuffed the papers, laptop, and emergency earplugs into my bag and made for Stony Creek. Snow squeaked under boots; vapor curled under my scarf. Every few steps I rehearsed neutral ways to open the conversation.
Hey, Luke, noticed you nearly cracked your phone in half with your quadriceps—need anything?
Too direct.
Radiator’s holding steady at sixty-eight. You look twenty degrees lower—want to calibrate?
Too weird.
By the time I hit the third-floor carpet, I’d drafted nothing usable.
Our door was ajar—standard two-inch buffer.
Light glowed. Inside, Luke sat at his desk, shoulders forward, textbook open but untouched.
His phone lay screen-down on the keyboard.
The rest of the room looked staged: bed made military-tight, gear bag zipped, even the stickhandling ball corralled in its pouch.
I could see the shoulder taping under his tank top.
He glanced up. Relief crossed fast, like a flashcard flipped for half a second. “Hey.”
“Evening.” I closed the door, dropped my bag under the desk. Radiator check—valve perfect. Good. “How were weights?”
Luke spun the athletic-training ice cup in one hand, condensation dripping onto a towel he’d spread logically across his thigh. “Weights were fine. Coach didn’t kill us.”
“Pulse and respiration confirm survival.” I toed off my boots. “Food acquired?”
He nodded toward the fridge. Two blueberry bars waited on my shelf spot, aligned like stalagmites. “Supply chain secured.”
I peeled off my jacket and resisted the obvious stall. Ask. Just ask.
I opened the fridge instead, grabbed one bar, turned, and leaned against the door. “Phone quiet now?”
His gaze dropped to the device as if surprised to find it still there. “Sure.”
Too fast. I unwrapped the bar, broke it in half, ate the smaller piece. “Quiet is an interesting metric. Three alerts earlier, then radio silence.”
Luke’s shoulders stiffened. He picked at the training-room tape around the cup lid. “Was nothing.”
My turn to raise an eyebrow. “You ice your shoulder for nothing?”
“That’s for practice.” He forced a half-smile. The gesture carried the vibrancy of a wet firework.
“It wasn’t just practice,” he admitted, looking down at his knees. “We dropped the exhibition against Vermont last night. 4-3.”
“I didn’t see a score alert.”
“Because we should have buried them. Instead, I lost the puck in traffic twice. Complete vision failure.” He crushed the paper cup in his hand. “Coach is making sure I feel it.”
“Statistical variance,” I offered.
“Garbage goaltending,” he corrected.
Silence chewed twenty seconds while the radiator ticked a metronome. Luke stared at the textbook page—statement of cash flows, bright blue heading. His finger traced the margin like reading Braille he didn’t understand.
