The Gilded Age First Watch Reaction S01-E08, So Much Backstories and Revelations

As a longtime fan of Downton Abbey, I am watching Julian Fellowes newest series, The Gilded Age, for the first time.

In The Gilded Age season 1 episode 8, the penultimate episode of the season, titled Tucked Up In Newport, The Russel's, sans George, spend some time in Newport, along with Oscar, Mrs. Fane, and others; Marian, by a lucky coincidence assist in resolving Mr. Russel's case; and we get two tragic back stories this episode: one for Peggy and one for Jack.
