Who would Twila take to the end?

In Vanuatu (Season 9), Chris wins final immunity and honors his pact with Twila by taking her to FTC and votes out Scout.

Before Chris officially decides to take Twila, he hears Scout (who's out of the challenge) cheer on Twila during the final immunity challenge along with the fact that Twila won't step down during the challenge. This makes Chris suspicious and he asks Scout if she and Twila had a pact to go to Final 2 just like Twila had with Chris. Scout says no and that's good enough for Chris but I wondered if Twila would rather go to the end with her day 1 best friend with a strong alliance instead of the guy who she seems to like and she has a strategic alliance with.

Twila turned on her alliance and seemingly sabatoged her game for Scout who was ousted from the Woman's Final 4 Alliance in favor of Julie. Chris of course benefitted from this move as well but it felt to me more as though it was to secure Twila and Scout's games than to secure Chris' game.
