ghost crew + thranto headcanons
The pairing of Thrawn's tactical brilliance with Hera's compassion and integrity made for a lethal combination. When they would willingly work together. Very much a 'this is our get-along shirt' type of situation.
Sabine has designed many pairs of crazy sunglasses to hide Thrawn's eyes on undercover missions.
'I wonder how much I have to annoy him until he snaps'
'Ezra that is a terrible idea'
And it was. After two months of annoying/pranking Thrawn with no reaction, a badly timed whoopie cushion prank ended with Thrawn yelling at Ezra for two minutes in incomprehensible, vicious Cheunh before refusing to speak to him for a week. Hera made Ezra promise that he would stop bullying Thrawn for the sake of sparing the rest of the crew awkwardness. Ezra kept that promise (for the most part).
Eli was horrified to find out that Ezra hasn't had a single day of proper education. 'I lived on a planet with zero resources because of the Empire, when would I have learned trigonometry' Eli offered to teach him some stuff, and Ezra actually ended up enjoying it. Not that he liked to admit it.
The crew often mocks Thrawn and Eli's as private school wankers, as the majority of them missed decent schooling because they had their childhoods during wartime. (no one risked making fun of Sabine however lest they be punched)
'Guys, you just need to switch the HDMI cable'
'Oooo where did you learn that, the Royal Imperial Academy?'
Both Hera and Kanan believed that Thrawn's reserved demeanour meant that he would be a good influence and keep Sabine, Ezra, Zeb and Chopper out of trouble during missions.
