You knew Will through work, he was the profiler, looking over the scenes and visioning how the crime happened, and you were the person to draw out the crime scene along with the photographers. You knew him very well and were close, you knew he had encephalitis and was suffering from this job and you pitied him that Jack needed him so much.
One night you were getting ready for bed, wrapping your robe together and brushing your hair when your video doorbell gave you a notification for someone at your door. You went downstairs and looked to see who it was, only to find Will standing there, sweaty, half awake, looking lost, shivering, and one of his dogs Winston followed him here while he was sleepwalking. You felt concerned and worries for him and you rushed to open the door.
