1:17 AM. Section four of the neuroanatomy review. The library quiet in the specific way it gets after midnight — not silent, but settled, all the casual students long gone, only the serious ones left in their islands of lamplight.
Lena turned a page and did not read it.
She was aware, with the precision of someone who studied awareness for a living, that she had not actually absorbed anything in the last twenty-two minutes. She had looked at words. The words had not become information. This was because Noah was sitting across from her and had taken off his jacket an hour ago and pushed his sleeves up, and she was a third-year medical student who knew in considerable anatomical detail exactly what forearms were and had somehow never made peace with his.
Focus, she told herself. Brachial plexus. Median nerve. Radial nerve. You know this.
She did know this. She could recite it in her sleep. She had recited it in her sleep, twice, which her roommate had found deeply alarming.
Noah turned a page. He made a small sound — not quite a word, just a note of interest — and underlined something in blue. Important, then. Not just interesting.
Lena looked at the top of his head, bent over his textbook, and felt the familiar specific weight of the thing she had been carrying since March.
March. Seven months ago, a Tuesday, a different library table. He had fallen asleep mid-session and she had kept studying and when he woke up he had looked at her, disoriented, and said her name in a voice that was still half-asleep — Lena — and something had moved in her chest like a door opening in a house she thought was empty.
She had closed it carefully. She had studied very hard for the rest of that semester.
She looked back down at her page. Section four. Cranial nerves. The vagus nerve: longest of the cranial nerves, wandering through the body, connected to more things than seemed reasonable.
Named for the Latin word for wandering, she read. Associated with the regulation of the heart.
She put her highlighter down.
Of course it is, she thought.
