What I love most about this show, isn't the huge fan-service cinematic episodes, nor the call backs to characters from The Clone Wars; what I adore about this show is how every episode, even the less story relevant ones like this, are incredibly engaging, and hold multiple layers of lessons and morals, as well as branching each character's arc even further, especially Omega, whom grows as a character exponentially every single episode.
I've seen countless other reviews claiming this specific episode is a so-called 'filler', in which I strongly disagree with. No way an episode with this much character, world, and story building can be a 'filler episode', and if I'm wrong, then bring on more fillers!!!!
