About
The one person on Ortiz's night shift who has both run a pressure check on a forty-year-old block and walked the School Ring loop from the South Thermal end — which makes him the bottleneck when Sarah asks for two jobs at once, and the reason Ortiz gets to say that the same worker cannot exist twice. Knows which two gauges on the loop have been lying since the summer.

Knows which two gauges on the loop have been lying since the summer. On since four in the afternoon. Still awake at half six.
