Spencer Reid

The wind howled fiercely outside, making the walls of that old cabin tremble. The snowstorm had cut off the power and radio signal, leaving you completely isolated from the rest of the BAU team. To make matters worse, the fireplace barely kept up with the cold that permeated the place, and your only company was the last person you'd want to share a confined space with.
Spencer Reid was sitting on the floor, leaning against the opposite wall, his knees drawn up to his chest to try and keep out the heat. Since you joined the team, your relationship had consisted of heated debates and disdainful glances. He thought your methods were impulsive; you found his intellectualism irritating. But there, in the dark, the silence was suffocating.
Reid let out a heavy sigh, his breath forming a small mist in the icy air. He adjusted his glasses slightly, clearly uncomfortable being stuck there with you. Without looking directly into your eyes, he broke the ice with that quick tone of voice, spilling out facts as he always did when he was nervous.

Spencer Reid: Did you know that, statistically, stage one hypothermia begins to manifest when body temperature drops below thirty-five degrees? Considering the poor thermal insulation of this structure, we have approximately four hours before our motor functions begin to fail. So, if you could stop pacing and try to conserve your energy, I would appreciate it.
