I agree he's got a snowball's chance in hell of getting back in, but I really think he's trying.
He's looking at July's success, realizing he's not gonna be able to take him down, realizing CG is dying, and then... before you know it... he's looking to roll back the clock, and his career, to a pre-CG state.
Like Zack, he's dressing it up as "Well, the problem has been fixed now," but we all know that's bullshit.
I think if they had a better work ethic (and, in Zack's case, his weird ideas about how to do everything and inability to listen to civilians were done with), they would get DC jobs. At least nowadays that their troons are getting them into trouble. Of course they suck and thus they failed at getting those jobs even as the troons are getting fired in the wake of Charlie Kirk's assassination. The indies were the proving ground to see how one works and interacts with the customers. Needless to say, they disappointed.
He's an old man by industry standards, he will be expensive compared to some inexperienced activist genderqueer trans blubberwhale that can submit work on time and works for cheap, he has a reputation of being an alt-right chud even if he tries to pivot, his return to DC will be flooded with outrage from Bluesky, he can't deliver work on time and needs wrangling - which won't be easy considering his ego and delusions, he is a pathological liar that starts and creates divisions within any group he affiliates with, he licks urinals, and there are years of embarrassing YouTube videos that are PR disasters waiting to happen.
That and the trannies ruling DC will walk if he gets rehired to DC.
So yeah, unless he somehow manages to give Gunn AND Zaslav the best blow jobs they have ever experienced, he isn't moving his fat ass from his Trashchat seat anytime soon.
I disagree with one point: DC would hire a conservative artist talent. If not now, in a year or two as the crackdown on DEI and the embarrassing attitude of the people of gender continues. Anti-Antifa raids, death threats and more will keep the trans "talent" in the news for all the wrong reasons. He will not be hired but not because he is an expensive conservative artist (as opposed to the cheaper trans trenders that get books canceled and refunded with a single post as that is more expensive on the long run), he will not be hired because, as you said, he is bad coworker, a liar, a disgusting idiot, an egotist and easy to start fights.
It does not matter if the trannies walk, if Bluesky erupts or whatever as long as he does his job well, on time, with minimal drama on his side and, in general, makes it worth it to keep him around. Problem is that he has been shown to not do his job well, he is never on time, he starts the drama all the time and is, in general, not worth it to keep him around.
The trannies could revolt but, at this point, most companies would be willing to take the hit for a good worker. He is not a good worker though.
