This is quite a few episodes after the fact; I believe it was in an episode before Elizabeth left for Lyndhur....I mean New York. Now, I thought that while Elizabeth and Roger were cousins of Quentin in PT, in that episode before Elizabeth went to Lyndhur....I mean New York, Quentin called her "sister dear". Now, I wonder if that was just a blooper, left over from when he called her that (as Judith) in 1897, or did the writers decide to change the relationship or maybe just plumb forgot. Actually, I like the though of Quentin being their younger brother and having inherited everything (save for the scraps tossed to his older siblings) by their father Jamison. It would be a rather ironic twist from 1897 when Judith got everything from Grandmamamama in NT, a few scraps tossed to Edward, Quentin and Carl (well, at least in the will Barnabas had Sandor forge). The fun thing to figure out is why did this happen? Just what did the older two kids do to tick off Daddy so that the youngest cleaned up? So many possibilities in PT! That's why I'm one who likes the story.
