Wonderful episode. It is realistic, from what I know of the social history--how servants were little more than poorly paid property without lives of their own. Sarah poses for an artist who doesn't care about how he uses people (or how art uses people). When Scone hangs both pictures in a gallery, side by side, Lady Marjorie and Richard are embarrassed. Ready to dismiss both servants--despite Roses' history, they reveal their total participation in the social class system. The only objection, upon reflection, is that this is uncharacteristic of Richard as we come to know him. In a later episode he is willing to stick up for servant--Mary-- because he can not deny his background as a preacher's son. All in all, this is a terrific episode.
