Greco has been silent for a long while as he mulled over the things that Greg said to him. As he mulled over it, he knows that Greg is right, his son is a burden to him and he should put him in a rehab center or kill him
However, as he keeps mulling about it, his conscience and his heart can not take it, just the thought of losing his only son breaks his heart, so it is not the feasible option that he could use
Putting his son in a rehab center is also a not feasible thing to do as it can not guarantee that the rehabilitation center can keep his son inside. He can always escape just like what he did in the past
As he thinks about it, he felt like his head is going to explode as it is his biggest dilemma
Looking at Greco's face, Greg knows that Greco is having a problem making a decision. Greg knows that Greco loves his good for nothing son, so much. But in Greg's opinion, Greco is a weakling as he can not make even the simplest decision.
