It's a different form of excuse. Because it was definitely gonna take those 15 extra days anyway. He's admitted more than that though, he's essentially admitted that he's a lazy dysfunctional loser who can't work, and also can't do this type of "work" either. The reason that he doesn't stay mindful of that and be grateful for the people paying for his continued existence while he does next to no work is that he doesn't need to. The enablers will keep the money coming regardless even while they're being treated like dog shit. Maybe it's a fetish thing.
Ya know, I'm not sure what everyone is so impatient for anyway. It's not gonna be some big thing, it's gonna be 1 extra position on that one martha scene. From the looks of the teaser it'll just be the dog dry humping her with her pants on or something, same as the Vera thing. EVEN IF it's a whole rework of the rest of that scene and it's proper sex, it's just that, one scene. And then another year to wait for another tiny 1 scene update. Big whoop.
