For whatever reason, the option to take the photo when Carmen trips is there, and you do get the photo, but that achieves nothing as the Fan Club chain is on hold until you finish the corruption quest (or enable (not just pass by the PTA) the Student-Teacher relationship policy - not sure, unable to check at the moment). At the very least, if Carmen and Oliver had sex in the office with you watching, you definitely achieved conditions for the Fan Club chain to start.
P.s. I never even considered "being nice" a possibility myself, actually.

Could be that, I suppose.
