This strikes me as a more mature Page of Swords. Rather than relishing the turbulence or adding to it by wildly waving a enormous sword she wraps up against it. This will protect her from being buffeted about in a continually reactive cycle.
The guidebook says this card is about asserting what is right and fair and acting with integrity. This young lady uses her grey matter and chooses her battles. She knows that if she doesn't no-one will listen when it really matters.
Her finger and thumb together seem to say 'speak your truth but do so in a measured way.' The grey behind her and the dagger carried low reminds me sometimes a 'bloodless' narrative is best.
Let us retreat when we can, not when we must.
