Loved the new episode. The defamiliarisation of Omega being fascinated with dirt is one of those things that makes you appreciate the world a little more than you already did. If you want to make a viewer appreciate something they take for granted, create a story where it’s taken away - and that scene drives home the effect of poor Omega having grown up on one horrible rainy planet in sterile white corridors her whole life so far.
Speaking of Omega, similarly to Ezra and Ahsoka, she’s a young character who actually acts her age - but unlike Ezra and Ahsoka, I see very few people complaining that they find her annoying. Maybe it’s because she’s the youngest of those characters and therefore in the realm of ‘cute’ rather than ‘immature’.
