For Oscar, every day is a day of fear and confusion. He didn't know what would happen that day or the next. Oscar really had no control over his life.
Every day Oscar only saw the prison cell filled with darkness and the naked body of the man. No sunshine, no birdsong, no soil.
After telling about his dark past, Peter's eyes widened in shock. He didn't know that his son had fallen into drugs and almost killed himself in a prison cell! All this time he thought that Oscar studied seriously in Sweden so he didn't have time to contact his parents for more than 6 months.
Just as Greta couldn't believe what she heard. Why didn't anyone tell him about the trouble Oscar was having!? Why didn't Clara say anything?
Oscar kept his back to them, not daring to see the look on their faces. Actually he wanted to know what expression Greta had on his face, but he was too emotional so he didn't have more energy to just turn around.
