like all things Q we are still in the discovery faze. Put it simply you throw in a new guy, this distracts from what was just done and provides a tool to remove someone unexpected. as people fuss over the sudden removal you switch it up and change the narrative again by putting in someone else so now the narrative is back on the transition not the actions taken. It's a distraction sequence that is extremely effective because it wastes so much of their time they can't concentrate. For all the dust they don't see the stampede.
