Specialist290 and
Veldmaarschalk: Perhaps.
Shuma: Perhaps she sees him as a sort of unlikely candidate for being an enemy to her "dear husband", and hopes that it will come as a surprise.
If, of course, he does what Adelaide hopes he does.
stnylan: If Adelaide was hoping for instant resaults, like Eberhard reading the diary, riding after the crusaders, and stabbing Guillaume in his sleep, she'll be disappointed.
I don't think I'll update tonight, but I will give you a list of important de Toulouse family members and how they are related (special for the Specialist

):
First Branch
Guillaume de Toulouse: Duke of Toulouse, Languedoc, and Mallorca
Beatriz de Toulouse (deceased): First child of Guillaume and Adelaide. Died very young.
Gaston de Toulouse: First son of Guillaume and Adelaide and heir to Toulouse.
Barnard de Toulouse (deceased): Illegitimate son of Guillaume. Drowned at age ten.
Robert de Toulouse: Son of Guillaume and Adelaide. Energetic and talkative.
Gaston ("the younger") de Toulouse (deceased): Illegitimate son of Guillaume. Died very young.
Second Branch
Hugues "The Elder" de Toulouse (deceased): An old courtier distantly related to Guillaume. Guillaume irrationally thinks Pierre poisoned him.
(by unknown first wife)
Hugues "The Younger" de Toulouse: Wed to Hildegrad de Bourgogne. Trusted courtier of Guillaume. A bit of a drunk and dislikes taking risks, but overall a good person.
Miquel de Toulouse: Highly opinionated and aggressive son of Hugues and Hilde.
Pierre de Toulouse: Wed to Euphrosine d’Anduze and later Delinda Taparelli. Guillaume's secret public enemy # 1 and "everyone's favorite tragic hero".
Bregida de Toulouse: Daughter of Pierre and Euphrosine. Quiet.
Pau de Toulouse: Son of Pierre and Delinda.
(by Oda von Pfirt)
Eberhard de Toulouse: Son of Hugues "the elder" and Oda. Clubfoot with little self confidence but a good writer and friend.
Peironela de Toulouse: Daughter of Hugues "the elder" and Oda.
(Please note that I haven't included everyone descended from Hugues "the elder". There are just too many of them to realistically include in the story.)
