Meh, not just Haley. I won't even try to dig up the comic, but Nale, in his "Wile E. Coyote" plan specified that the scissors Sabine was to use to cut the rope on the obligatory 10 ton weight had to be neither silver nor iron. So even her lover and party leader has no clue as to which she is.
So yeah, the comic represents this ambiguity plenty.
Reinforces? Those are her save bonuses after counting in the Holy Word penalty. She has good odds to ignore the banishment portion of the spell.
