2^nd paragraph: the light finds fault with mother's white aging skin without makeup, color or adornment.  It's an instance of nature troubling mother, as nature troubles son by being vibrant with evil directed towards him.  Mrs. Sol is the sun.  Age and humiliation have traumatized the parents.  Isaac the prince is the savior (angel of light—this is humiliating).  His nickname indicates resentment and humiliation.  Mrs. Sol gives off light (but it's garish), like merciless sun does, but mother is drab and does not take care about her appearance.  It seems women their age cannot win if these are their only two options for appearance.  This is the way it is.  It neither is nor is not the parents' fault. ...  Mother is the blank glaring light on whom/which is projected son's inner life, or each parent's inner life (mother defers to father).

3^rd paragraph:  Loss of life‑current between two stations (train) (parents and son).  Alienation: "dutiful beating of one's heart"—"dutiful" (with one all the time) and "rustling of papers"—alienated in public.  Waiting.  In public.  Rain.  Mud.  Another attempted suicide, this time on the birthday visit.  What about the parents' judgment in not leaving the present?  Anxiety about his not getting it (an object).
