He had lost a total of ten months. Not a long time when you've already been around for two-hundred-seventy-five years.
He spent the first five months reverting to type. Seventy-nine murders, twenty-three tortured but still breathing, sixteen raped. A drop in the bucket, comparatively speaking.
Then he disappeared for five months. A never-ending "vacation", enduring tortures even he had never dreamed of. Tormented with no possibility of absolution.
Ten months. A second when you're immortal. An eternity when you've destroyed everything you've ever cared about. Being back is so much crueler, because at least before he didn't have false hope.
