I'm beginning to wonder what exactly Mom's agenda is; I believed prior that she wanted Seiichi and herself to have an exclusive and unhealthy life together, but after she basically spilled to her husband that the kid is essentially the root of all her problems, and that her actions as of late have done nothing but drive a wedge between her and her son's relationship, I don't know what she's going for anymore. I guess if she really is nuts, there really doesn't need to be any rationale.
