For the record, the Lwaxana episodes are amongst my favorite of TNG. The exasperation she manages to inflict on Picard is fucking delightful. The one thing that he has no idea how to deal with. Delightful.
All bow their heads for the glorious Lwaxana Troi, Daughter of the Fifth House, Holder of the Sacred Chalice of Riix, Heir to the Holy Rings of Betazed.
Yes, Lwoxana Troi only has three children: Deana, Kestra (deceased), and her son with Jeyal (who he tried to take away from her).
She does wed extremely rapidly, but I will not have this man besmirch the holder of the holder of the Sacred Chalice of Rixx and heir to the Holy Rings of Betazed.
