The drugs affects on that night

Even though Oscar wanted to talk, he didn't try to talk anymore. He stopped it. Because he knew his brother needed time to accept the situation. That's why his mother asked him to stop. It's too much for his brother to grasp things. He returned home after two years, and the first thing he heard was his brother trying to molest someone. 

Magner needs time. Oscar understood it. 

Just like him, even if Luciana gets out of the trauma, he would be her constant reminder of that particularly unfortunate night. He will not let go of this incident. It's all because of the black ocean group. His eyes turned red at the thought of them. His family was hating him, a woman has to go through hell because of them. He needs to do something to it. 

"What shall I do now, mom?" Oscar asked as he looked at the empty stairs. 

"We will decide that during dinner," Ella said giving him a side glance.
