Wow, the addition of dialogue on those pages changes things COMPLETELY. When I saw those unlettered I was thinking SHE got shot. Or at least he attempted to shoot her. Weird though, she's clearly being kept isolated, and yet he allows her to have a camera?
I think Polaris is about to do something stupid, she probably wants to finish that fight with Magus and will jump at an opportunity to do so. Though the others would not go along with that, and Snow knows that, so he's only talking to her.
And yeah, obviously a reference to Card, I do like how both characters present their views and no agreement is reached. It is a tricky situation, where you choose to draw that line between art and artist.
