To me, the only wasted opportunities with Joe, are more scenes making him watch you fuck Vanessa, or a scene telling him to take a hike so that more screen time can be spent on better things.
But hey, that's just me.
I know this won't be the case, so I'm just hoping that there won't be
too much drama when Joe realizes that Vanessa is truly no longer his girl, when he sees the MC and Vanessa have gotten much closer. I really don't care to see a scene with Joe whining about it the whole time, and if such a scene exists, I hope we can put him in his place at least.
