The days followed, turning into a week.
During this period, however, Isaac didn't give Johan a single minute's rest.
Every day, Johan did push-ups, sit-ups, squats, pull-ups using the bars that covered the ventilation ducts in his cell, as well as running.
Every day, Johan ran.
Sometimes he would run for a few minutes, and when he got tired, Isaac would smile that mischievous smile, and Johan would stare back at him with pained eyes.
"Is this serious, man?" Johan would ask.
"You know it is, little grasshopper... Boys, get him!" Isaac retorted, as his fellow Purgatory members ran like beasts after Johan, who ran away from each one as if his life depended on it.
For minutes on end.
Sometimes even for hours.
"So... Is that Sabaid...?" Johan asked once, as he ran, almost snorting.
