Unless I missed it, that part of the comment wasn't mentioned in the blog. Courtney flipped on Duncan because she thought she would be going home otherwise, not strategy.

Furthermore, Courtney would realize in an auto-elimination type final three that she and Duncan could team up, where the other two would team up against her otherwise.

I know it's the results of the blogs, but I just think the reason could be a bit more fleshed out in terms of considering the why she would make an emotional move over a strategic one.
