The backgrounds (and continuing stories) of some of these kids are just heartbreaking. Given all that she's experienced, I felt bad for Morgan when her grandparents "joked" that she couldn't live with them. She looked like "Ha ha... oh wait, really?" With the parental abandonment (fuck you, Morgan's dad), I would think her grandparents would be a little more careful about saying that kind of thing, since they seem to care deeply about her well-being.
I was ambivalent about Monica's cheerful characterization of Morgan as a people pleaser. Her takeaway seemed to be that she could get Morgan to agree to anything. But surely Monica would understand that Morgan likely continues to fear abandonment by those who are supposed to be on her side. I find it tragic, and I hope that Morgan is able to forge stable relationships going forward.
