Chapter 6: The Prisoner - S1-E6
Other mistake: Since they received a distress signal from a beacon, the X-wings...destroy the station the signal comes from, instantly. Maybe it's better not to ask for help (Notice the fact that they continue to attack it and in the concept art at the end of the episode the station is shown as exploding, not just the gunship they were launching).
Chapter 6: The Prisoner - S1-E6
Other mistake: Everyone Mando fought with at the ship turns up alive at the end of the episode, but it's shown in the fight with the devil dude that the doors closed all the way and there's no room between the two sets of doors. There's no space for his head not to be popped like a melon. (00:30:00)
Answer: In (non-canon) Legends, Thrawn was the central character of a trilogy of novels by Timothy Zahn. He was a Chiss officer in the Imperial Navy, who rose to the rank of grand admiral despite being non-human. Thrawn was brought into canon in the Star Wars Rebels series, where he commanded the Empire's Seventh Fleet and led the occupation of Lothal, which was opposed by the series' protagonists including Ahsoka Tano. In the final episode of Rebels, the Jedi and Rebel Ezra Bridger commands Purrgil space whales to drag Thrawn's Star Destroyer into hyperspace, jumping to an unknown location with himself and Thrawn on board. The final scene of the series shows Ahsoka Tano and Sabine Wren leaving Lothal to search for Bridger, and presumably Thrawn.
