I think there's a lot more to Victoria's game than we're being shown. When you're right on all the votes and the alliances have been as fluid as they have been, she's likely playing a more subtle version of Sandra's "anybody but me" strategy. Her individual interviews and responses to Jeff's questions show her to be pretty game savvy. She has no set alliance, hasn't won a challenge, and doesn't have any advantages. If it gets to the final vote and things continue as they have been, her argument that she put everyone on the jury would be a compelling one.
