Elizabeth is a real Chopin fan! In ep. 2, she played his C-minor Prelude. Tonight, she's playing the Etude no. 3 in E major, Opus 10. She and Carolyn look very romantic in their robes and with their hair down.
Roger blusters about returning THE PEN to Burke--but where is it?
Elizabeth seems to have had premonitions at various times in her life. Is this something that runs in the family? Surely she is thinking of Roger when she tells Carolyn, Perhaps the lamb has already gone to the sacrificial altar. But later on, when he returns home, she says Bill told her that he (R.) lied at Burke's trial and that he in fact was driving on the night of the fatal accident.
Maybe Sam was improvising about where Bill's phone was.
I like those segues: The tall foyer clock at Collinwood strikes 11:30, and in the next scene, the clock in Roger's office does too. Later, Bill's phone rings and rings, and in the next scene, Carolyn and Elizabeth fondly recall a Halloween trick that involved a ringing phone.
