On total divas, a guy from Talent Relations delivers angle developments to the women wrestlers. Is this really how they learn of storylines or is this just for Total Divas and to cut down on the amount of WWE producers on the show?

​The more important question is why you're watching Total Divas.  
Regardless, the entire show is basically a scripted TV show, so essentially anything you're watching on it was manipulated for the purposes of TV.  And yeah, I don't think they want to have actual WWE production people as characters on the show.​
