The set of choices I listed above if followed directly lead to unlocking the 11th CG that's in the middle of the second page, a scene that happens directly after you reject Jilly's confession in place of Jilly's scene that's supposed to happen there.
The 12th scene is one that happens after the first encounter with Ruby and happens depending on if you favour Jilly and Tari equally or not, which I believe you have already, correct?
