Bab 80: G. Callen x Doctor!Reader x Kelly Severide

"If you're paying I'm totally in." Your older brother laughed. Night fell, and you began to close up. You walked to the supply room, you noticed smoke fluttering under the door. You pressed your hand against the door, a trick your 'friend' Kelly Severide had taught you. The wood almost burnt your palm. You backed up, leaving the door shut. Knowing it would cause a flashover which would kill you. You fumbled for your phone while running towards the closest exit, the doors were chained shut. "What's your emergency?" You gave your location and how bad the fire was, as well as how there was oxygen tanks. You heard the sirens of the fire engines, you glanced out the window pausing in your attempts to break the window. You waved your arms; the smoke was getting worse. You coughed heavily and got lower to the floor, trying to find some oxygen. There was yelling outside. You could have sworn you heard your brother yelling at someone. Your eyes began to flicker and grow heavy. There was a crashing as the door was broken down. "Y/N!" Kelly grabbed your arm and tugged you into his arms as Mills, Casey and Herrmann checked for others.
