[196 Witherspoon Street — January 16, 2005, 9:00 PM]
The knock was three sharp raps — Cameron's knock, the one Isaac had catalogued in the Memory Palace alongside her vanilla perfume and the specific cadence of her footsteps in the hospital corridors. He'd been sitting at the desk reviewing Vogler's latest departmental memo — a three-page document outlining "enhanced productivity metrics" that translated to we're counting your breaths now — and the knock pulled him out of the bureaucratic weeds with the particular urgency of an unscheduled visit.
Cameron didn't do unscheduled. She planned. She texted ahead. She asked if it was a good time because respecting boundaries was woven into her DNA the way diagnostic skepticism was woven into House's.
Isaac opened the door. Cameron stood in the hallway with her coat still on and her car keys still in her hand and an expression that Social Deduction decoded before she said a word: resolution preceding confrontation, decision already made, emotional state elevated but controlled.
"Can I come in?"
"Of course."
She entered. Didn't sit. Didn't take off her coat. The keys went into her pocket — one hand freed, one still gripping something — and she stood in the living room between the medical textbooks and the empty walls and looked at Isaac the way she'd looked at the apartment two weeks ago. Cataloguing absences.
"I need to talk to you about something."
Isaac closed the door. Leaned against it. The distance between them — eight feet, the length of Burke's living room — was wider than the space suggested.
"Okay."
"You analyze me." Cameron's voice was steady, pitched in the register she used when delivering difficult diagnoses to patients. Professional. Compassionate. Firm. "Every conversation. Every dinner. Every time we're together. I can feel it — this... thing you do, where you're looking at me but you're also looking through me, like you're reading a chart instead of seeing a person."
The accusation was accurate. Isaac couldn't deny it because denial would require lying about something Cameron had experienced firsthand, repeatedly, for the past month of their relationship. Social Deduction was always on. The power operated at baseline — passive, continuous, feeding Isaac emotional data about everyone in his proximity. Cameron's stress hormones, her micro-expressions, her vocal cadence shifts — all of it processed automatically, all of it filed in the Memory Palace, all of it creating an asymmetry between them that no amount of romantic intent could bridge.
"I know," Isaac said. "I'm sorry."
"You said that last time. After the restaurant, when you admitted you'd been reading my body language all through dinner." Cameron's hand came out of her pocket — empty, the keys left behind. "And the time before that, when you told me you'd noticed I was upset about a patient before I told you. And the time before that—"
"I get it."
"Do you?" She stepped forward. One step. The gap reduced to six feet. "Because from where I'm standing, you keep apologizing and nothing changes. You keep watching me like I'm a specimen. Like I'm a case study with feelings."
Isaac pushed off the door. Walked to the kitchen. Poured water from the tap because the coffee maker felt too domestic for this conversation and the refrigerator held nothing but leftover Thai that was three days past acceptable. The water was cold. He drank it standing at the counter — the same counter where he'd eaten Cheerios on his first night, standing because the empty table was worse. Two months later, the table was still empty, and the metaphor was getting heavy.
"It's not voluntary." Isaac set the glass down. "The way I process people — it's not something I choose to do. It's how my brain works. Like the memory thing. Things stick. Including... impressions."
"Impressions." Cameron crossed her arms. The defensive posture clashed with the vulnerability underneath — Social Deduction reading the combination automatically, the power doing exactly what she was accusing it of doing. "You called them 'impressions' at the Garnett case too. When you knew the patient was lying before any tests confirmed it."
Cameron had been paying attention — connecting data points, building her own version of House's notebook, tracking the pattern of Isaac's impossible perceptiveness across months of shared experience.
"That was different."
"It wasn't. It was the same thing you do with me. You see things you shouldn't be able to see, and you can't stop seeing them." Cameron's arms tightened against her chest. "When you kiss me, Isaac — when you're supposed to be present, supposed to be with me — I can tell that part of you is still analyzing. My heartrate. My breathing. My... I don't know what. But you're always watching. Even when your eyes are closed."
Isaac had nothing to say that was both true and safe. The truth — I have a supernatural ability that reads human emotions through physiological markers and I literally cannot turn it off — was impossible. The safe response — I'll try harder — was a lie they'd both recognize.
He tried something in between.
"I don't know how to stop." The words came out quieter than he intended. Not performed. Not calibrated. Just honest, in the specific way that truth sounds when it escapes through a crack in the wall rather than through an open door. "I look at you and I see... everything. The way your jaw tightens when you're trying not to cry. The way your breathing changes when you're about to say something difficult. The way your left hand reaches for your right wrist when you're nervous — you're doing it now."
Cameron's left hand dropped from her right wrist. The gesture had been unconscious — a self-soothing behavior she probably didn't know she had. Now Isaac had named it, and the naming made it visible, and the visibility made it feel like surveillance.
"See?" Her voice cracked. One word. The crack was worse than shouting. "That. Right there. You see things about me that I don't see about myself, and it's not flattering, Isaac. It's frightening."
Isaac looked at her. Tried — genuinely, physically, with the focused effort of a man fighting his own neurology — to see Cameron without reading her. To look at the woman in his living room and perceive nothing beyond what normal human eyes perceived: hair, face, expression, posture. No cortisol signatures. No vascular flush patterns. No micro-expressions translated into emotional probability matrices.
The effort was like trying not to hear music playing in the same room. He could reduce the volume. He couldn't find the off switch.
"I'm trying," he said.
Cameron looked at him for a long time. Social Deduction fed him the reading despite his best efforts — sadness dominant, resignation emerging, affection still present but receding, decision crystallizing — and the cruelty of the power was that it showed him exactly how she was leaving even as she stood in his living room.
"I know you are." Cameron picked up her keys from her pocket. The coat stayed on — she'd never taken it off, which meant she'd arrived knowing the conversation would end this way. "I care about you. I think you care about me. But I can't be in a relationship with someone who sees me more clearly than I see myself. It makes me feel... transparent."
The word hit with the precision of a scalpel. Transparent. The same word Isaac used internally for his most dangerous power. The Transparent World — the ability that stripped away surfaces and showed him the machinery underneath. Cameron had identified the essential nature of Isaac's condition without knowing its name, and the accuracy of her perception was a final, bitter confirmation that she was exactly the kind of perceptive, emotionally intelligent person who could never survive a relationship with someone like him.
"I understand," Isaac said.
"Please don't analyze that." Cameron's smile was fragile — the smile of a woman trying to exit with grace when the exit hurt. "Just let me leave, and let me feel whatever I'm feeling, and don't tell me what that is."
Isaac put his hands in his pockets. Kept them there. Kept his mouth closed. Kept the analysis — which was running, which was always running, which showed him Cameron's grief and her relief and her affection and her anger in a cascading waterfall of physiological data — locked behind his teeth.
Cameron walked to the door. Opened it. Turned.
"For what it's worth," she said, "you're the most interesting person I've ever met. I just wish I could have met you without being studied."
She left. The door closed. Her footsteps faded down the hallway — the specific cadence Isaac had memorized on his first day, the rhythm that had meant warmth arriving and now meant warmth departing.
Isaac stood in the kitchen with the empty water glass and the empty apartment and Cameron's cat magnet grinning from the refrigerator — WORLD'S OKAYEST DOCTOR — and the silence was total and familiar and exactly what he deserved.
