[@deadpixel101] I think the general reaction would be suspicious at first because Loretta is a Mage. Per NPC:

1. Kass would poke at Loretta for thinking she could ever be included on Knightly wagers.
2. Federo would tell Kass the reason she is being off-putting is because she feels threatened - which would send Kass biting at Federo instead of Loretta.
3. Dane the oldest of the group cares very little about the squabbles between Knights and Mages. He would be for Loretta joining so long as she wages something equal to the Knights. 
4. You can also control Griff in this conversation if you'd like, he would speak last and support Loretta - Griff is about solidarity, integrity, and understanding. Therefore, he would not create a dividing line between his team and any other power in the room. He would only ever identify what needs to occur in order to construct the best possible outcome for the best chance of winning while never compromising his Faith or the mission of Belisio.
