No surprise if Parvati made the Final 3. Although I'm not a Parvati hater, I can see the advantages for anyone (such as Cirie) to bring her along. She probably isn't all that popular, and doesn't really have much game play (other than flirting). So a real strategist would feel free to bring along a non-strategist along -- heck, bring along two! It's perfect!
Personally, I think James would be the only lock to vote for Parvati if he wound up on the jury. Others might be more likely to vote for someone such as Cirie (if she got there) or Amanda (if she proves she has more skills other than hooking up with the right guy).
