Roper and Caesar continually address Colby (a lawyer) as "Shamus". A shamus is a private eye; the word they likely meant to use is "shyster".

When Nora returns to her house with groceries, she turns the inside light on, then off. But when the room goes dark, the outside "moonlight" doesn't come back until a beat later. Nora then crosses the room to turn on another light, but a beat before she hits the switch, the "moonlight" turns back off.
