Darling Misterioso,
I'm hardly the authority when it comes to Quentin, but my impression as re canon was that after Amanda's death, Quentin had fixated upon Daphne as his one-and-only. After the happy ending for the 1840s Quentin and Daphne, my impression from Sam Hall's notes was that Tracy, the new Kate Jackson character, had the potential to be written as a new love interest for Quentin--either as Daphne's reincarnation or in her own right.
But then, monogamy isn't really my bag either, so what do I know?
love and tapioca pudding,
G.
