We have only tipped the iceberg. This is such an emotional complicated story. I cry every time I watch this series, but there is so much love to come. You said you wanted to know what made George come back to Charlotte, and we will see it eventually. Brimley has my heart, and I love getting to see new sides to Lady Danbury and eventually Violet. I can't wait until next episode.
Side note: Charlotte is not taking drugs. She is sniffing snuff.
