Vince's Time Wasters 9 is needed for Vandeel to appear at the gym
I've definitely done Vandeel, I'm pretty sure I've done Vic's Bro Chat 9, but I'm not 100% on the Special Investigation Intermission. I offer to hang out with Kubas a few times and 2 out of 3 of them involve him stopping to press me into his chest. That just raises my lust and repeats in a loop which leads to a gameover.
