Page 52 of the Mouse Guard manual states "if your character's actions in the game reflect his Belief, you earn one fate point. You may get this award once per session." [Example follows]
Page 53 states "It's hard to quantify, but if you play against your Belief in a cool and dramatic fashion... you earn a persona point."
I interpret this as meaning you can earn both the Fate point and the Persona point, acting for and against your Belief in the same session. Did I get it wrong?
