Honestly I liked the episode and I agree that the Spitfire and Fleetfoot were wrong about what they did but I still see them as respectable ponies. Despite the lies they fed Rainbow and tossing Soarin to the side, in the end they were still fairly good, because the two both realized everything they did they felt kinda bad for it, they apologized about it took Soarin back and Spitfire even thanked Rainbow for pointing all this out and telling them off. In the end they grew as a team because of Rainbow putting them back into place. Spitfire and Fleetfoot recognized they were wrong. It doesn't exactly mean that everything they did was still okay but learned not to do it again and therefore not too bad. It seems like Fleetfoot and Spitfire learned a lesson here instead of Rainbow Dash.
