I’m having some trouble placing some of the episodes, so feel free to share you thoughts:

Episode 1 - 20 BBY, during the Nightsister Massacre that happens in The Clone Wars Season 4 Episode 19.

Episode 2 - This one i have no idea where to place it. At first I thought it was early imperial era since we see Venators, but at the same time it doesn’t make sense because Morgan wouldn’t have aged so much in 2 years. The comics also confirm Thrawn became an Admiral in 9 BBY (which i thought was being retconned). Maybe the Empire just kept using Venators and we just never saw them? Not sure.

Episode 3 - 9 ABY. Since Bo-Katan answers the distress signal, it’s safe to assume she sent Ahsoka there almost immediately, which would happen shortly before The Mandalorian Season 2 Episode 3.

Episode 4 - 19 BBY, the day after Order 66 and Revenge of the Sith. More specifically, when Barriss is awaken there’s a lot of rain in Coruscant, which we see in Revenge of the Sith when Vader is getting in his suit. I place it between episodes 1 and 2 of The Bad Batch.

Episode 5 - 18 BBY. That’s purely going by Wookieepedia since it could happen basically any short time after Episode 4. I like to think a few months passed and i place it after the final Ahsoka episode of Tales of the Jedi.

Episode 6 - This one is also kinda tricky. It has to be after Obi-Wan Kenobi so after 9 BBY. I just placed it right after Obi-Wan and Jedi: Survivor, not sure when else to place it. As for Barriss aging a lot, im pretty sure it has to do with her constant use of force healing.
