* By avoiding Siesta's crush (an easy thing to do, in this wolfy case), she's left out of the romantic game if not the whole story, and might find a nice commoner man among the serving staff or back at home. One might have to ward off an over-eager noble boy or man, though.
* That pretty much leaves Louise and Tabitha.
* For Louise, Wardes might work, if you manage to keep him from succeeding at murder. I've read that he doesn't die in the original light novels, and instead travels around with Foquet researching information on the Void users and their familiars. Maybe he can be reformed?
