Jade is an absolute idiot

This man rolled in, riding in the back of his car. I'm willing to bet his business partner did 90% of the work on the "quantum algorithm" business that they sold.

He spends the whole show quoting pop science, meta physics, but really doesn't know anything.

Even his past life self revels in trolling him. His ventriloquist just screams at him to terrorize him.

He stares at symbols, stares at numbers, complains, never figured anything out.

Jim had to clue him in to the musical scale. Tabitha had to clue him into... Everything else.

Those that think that he was an important character, or that he had some great development, what exactly were those developments? He just seems like your typical elitist pseudo-intellectual.
