Beth saves Jenny from Quentin. All this happens yards away from Jenny, but she never knows. Later, down in the Old House Drawing Room... what a moment for Quentin to "propose" to Beth! I'm murdering my first wife so I can marry you, you can thank me later! And this is how I deal with marital problems, lucky you! Good for Beth, protecting Jenny with her own life. I wouldn't have expected that much from her, considering how she's spoken to Jenny.
How flexible time is for Jenny-- she sees the coffin minutes after having heard Quentin, and thinks he's inside. She mourns him so much it's painful to watch, but she went there to kill him.
Written by Sam Hall. I haven't made enough notes to get across that this is a GREAT episode, and why. Marie Wallace runs away with this episode. She must have been exhausted afterward. So much intensive acting in 21 minutes. We zero in on her character, and her internal world, and we'll certainly never forget her.
