Thank you for your compliment!! *hugs*
Ezra would totally be over-excited about the wedding. He would start collecting stuffs from all around the Rebel base, getting stuffs from what little resources they can spare for the ceremony. Maybe Zeb and Kallus let him do it in the Lothal fashion? It is an important place to all of them and where they first met.
Each of the Ghost crew give something as their wedding gift. Rex give Zeb and Kallus matched guns (he thinks it’s the ultimate romantic thing XD). Maybe Rex called Gregor and Wolffe over and Gregor can be their cook while Wolffe can wash dishes (he is still not a fan of having “fun” but he shows his support doing backup chores)
Ahsoka is totally going to officiate it.
Kallus send his wedding picture to the 7th fleet just to spite his former colleague.
Glitter and confetti exploded on Thrawn’s face when he opened the envelope with the wedding picture. (Thrawn: I’m not offended. This is actually… very artistic.)
