Why do you think David didn’t tweet about Twin Peaks yet ?

I don’t know, the last time he was asked about Twin Peaks during a panel, he was scared to say something and be reprehended by their lawyers. We know he has mastered the art of saying things he shouldn’t when it comes to his shows (wife gate, Mitch’s return…) so maybe he prefers to stay silent than saying something he would regret. That’s his explanation as to why he doesn’t tweet much in general anyway.
The return of Twin Peaks is still shady and they protect their communication a lot so David better not break it!
