1. Grogu is a character with agency now. He is capable of doing things. He's no longer just a cute sack of potatoes that gets put in scenes that make you go "Awww..." The way he just casually force slammed that Alamite on his way out of the ruins was such a great "I don't have time for your bullshirt right now" move.
2. I love what they're doing with Bo-Katan. She's disillusioned, she cynical. She thinks Din is silly for believing in these things. Yet she's still helping him because she knows that Mandalorians are stronger together and however weird she may view the tenets of his sect, he's still a Mandalorian. They kind of need one another at this point: she needs his earnest belief in the tenets and the creed, he needs her knowledge and experience. When he gives her that "This is the way" after she talks about her father dying defending Mandalore, there's no cynicism or dismissal there. It's a genuine moment.
3. On that note, the Mythosaur reveal at the end. So awesome. Bo-Katan talks about how everything is myths and legends and then...the supposedly extinct symbol of her people starers her right in the eye. Great way to end the episode. .
