Andy’s reassignment

Why was Andy reassigned to the other station after Maya’s demotion? The explanation is that Maya and Andy were insubordinate and to give Andy a place outside of 19. But did it have to do with drama on the set? A way to test out new characters? The stations always end up on runs together anyway, so she’s not working her way up a new station.

Edit to add: Duvall sucks?!
