Yeah I think it's an Affection issue...what is yours at? Cause I don't think it's possible to get that scene via the corrupt route, unless the android version is off...
i.e you:
-Kill the cops at the mall
-Smash the monster into the building
-Kill the PM security guards mindcontrolled by Jake
And then during the interview end up denying or being a menace, in which case; while you still get the Prison Sex Scene and the Halfway point Interview Sex Scene, her Affection achieved the negatives after doing the interview and even if you do try to justify yourself, you still only have a grand total of 2 Affection points.
Upon doing the promotion police cruiser ride with Brianna, you can suggest doing something more, and she ends up saying she's not in the mood, but she'll buy you an expensive dinner; dropping you off. Mission end.
