Just thought I would toss something out for thought. No one at the table has treated her with anything but a little annoyance at the attitude. Wren traded  barbs with her, but it was probably more because of said attitude than any hostility. She's traveled to lots of places, seen lots of things and has probably learned that it's action and the individual that determines if trust may be an option, not heritage. If the watch called everyone in for a job, there is probably some trust from the watch, at least, and that also set part of her mindset with the party in her eyes. Considering that "half" anythings tend to get tossed into one big pot of dislike and distrust (among other emotions), if a half-giant isn't going to bother her, a half-demon who might, just might be trying to stay in the light isn't going to. She'll trade snark and insults, but until something appears to create an active dislike or distrust, she'll give the benefit of the doubt.
