For a character who seems so inclined toward deceit, it feels like she should flee from the fight when it becomes apparent that she can't win. Whether it's when her sappers are all dead and the gate is still up, most of her troops have been killed, or her own health just goes low enough, there should be a point where she recognizes that she's lost and just flees to try another day.
In WW2, Japanese military commanders and soldiers would not flee/surrender upon defeat in battles. Upon knowing they had been defeated in a battle, almost all of them would not hesitate to die or die attacking, unless expressly ordered to retreat. Very, very few would flee from a battle or surrender. That has nothing to do with how inclined they were toward deceit. We all know, Japanese imperial navy in WW2 were really good at deceit.
I would have lost any interest in recruiting her as a companion, should she have the character/personality that enabled her to flee upon defeat.
