Zane has been watching the monitor for so long that the waveform has imprinted itself behind his eyes. The green line rises and falls in controlled arcs, a mechanical reassurance that she is still here. The ventilator cycles with predictable precision. Oxygen saturation holds. Blood pressure fluctuates within the range the doctors told him is acceptable.
Over three days he has learned what is routine and what is not. He has learned that machines speak, and that survival often hides inside small deviations. That is why he sees it.
The heart rate does not spike and it does not trigger an alarm. It simply shifts. It rises by a handful of beats and does not return to baseline. It holds there, wavering, trying to find a rhythm that does not belong to sedation.
He notices before he allows himself to hope.
