I vote for him pissing his pants, slipping in a pool of his own piss, and then falling and smashing his head against that sink he was carrying in that picture back when he bought Twitter.
Imo, instead of asking why he didn’t step aside, I think the fault is on the studio executives for wanting to go in that direction in the first place. They clearly wanted a different direction to classic Trek, otherwise JJ wouldn’t have been their choice.
I haven’t watched his videos in a while but isn’t he being sued by Billy Mitchell? I assumed his videos were more out of spite than actually chasing drama.
