This is why she's agreed to be saddled with the animal at all—the look of pure, unaltered affection in Ellis' face when he addresses Ruadh, and how it lingers there still in his face even after. The mabari is important to him. Obviously she knows that; they have spent a great deal of their time reading Ferelden folktales and histories, and she would consider herself rather well educated on the point of that people's attachment to their dogs, particularly their clever war dogs. But there is a difference between reading a thing in a book and seeing it plain on Ellis' face. That is particularly true when his only other souvenir from Weisshaupt seems to be the faintest air of melancholy.

It would have been unthinkable to turn down such a heartfelt gift as Ruadh's company, nevermind the annoying semantics implicit in the whole arrangement.

So despite a great air of being put upon—"Oh, very well."—Wysteria surrenders her hand to his guidance.
