I don't quite follow the story line. To me it sounds like a fight/argument/confrontation with a spouse I wouldn't want in my life anyway.

But it sounds like the son is at least 10 years old, it sounds like the spouse cares about the boy (shields him from his own drug use) so he wouldn't harm him; frankly, it sounds like it will be a matter of only a short time before you hear from the boy, if not from the spouse.
