He ran. It used to be because he loved to.
But now it WAS TO escape his demons. Now he ran when he got home from work.
He ran.
If there was an especially brutal crime scene,
He ran.
If a suspect was killed, He ran.
And when the nightmares came,
He ran.
He used to dream of running forever never stopping for anything. Now he DREAMED of all the VICTIMS he COULD never save. Now he ran till the sun came up or he PASSED out from sheer exhaustion. Whichever came first.
