Does Din know that Gideon dies? How does Luke know Vader’s alive in Empire Strikes Back? His ship was shot down in space…
You all keep saying plot hole, it’s not a plot hole.
The difference with ESB is that there was a time skip of 3 years in between ANH and that movie, by which point Luke would have has plenty of time to figure out Vader was alive. Mando doesn’t have any time in season 2 to figure that out offscreen, he’s on a mission the whole time. It is a plot hole.
Except we don’t see the entire conversation between Boba, Fennec, and Din as they get on Slave I, fly to Nevarro, then as Cara boards Slave I and they fly to meet Mayfield. There’s plenty of off-screen time to assume a conversation takes place.
Lines in Chapter 15 could also be changed and cut around to “where they took him” instead of saying Gideon by name if it’s THAT big of a deal to you, but it’s something that will easily be assumed and then character development and raising stakes can be preserved.
Our lead character making sacrifices, showing growth from when he refused to do the same action in the previous film’s climax, is a far more important aspect to the story being told, and has more bearing on the primary relationship between Din and Grogu.
