Gideon is established as still being alive when he meets Bo-Katan, and it’s not like he starts hunting Gideon prior to Grogu’s capture… could be that Grogu’s capture is what establishes Gideon as being alive at all. Boba might even mention it, I know he mentioned Din being hunted.

The tanks will be re-introduced and explained if and when they become important, and everything we learn about Cara in The Siege is re-established in Chapter 15. Grief Carga was given closure, and we don’t really get any character development with him, Cara, or Din in The Siege.

So, while the tanks are fun, and seeing familiar faces that don’t contribute to the story or character development is fun, I think story beats and major character development to the protagonist should be prioritised.
