I’m confused by Sadie’s belief: A guardmouse needs to be able to think with her head and act with her heart.
I puzzled for a moment over how that works out in game terms. I decided that it meant a guardmouse should consider situations carefully and rationally, but when it came time to ACT, s/he should follow her heart instead of her head if the two conflict. So in game terms she would act in accordance with her belief if she did the thing that ‘felt’ right regardless of what logic suggested was ‘best’, i.e. helping Conrad when he was in danger even if it endangered the mission. On the other hand, following her head instead of her heart when it came time to act would go against her belief.
However, the rule manual says on page 50:
If Sadie had stayed and fought with Conrad, she would have been playing against her Belief.
That would be ‘acting with her heart’; how could it go against her belief?
