So I could imagine Han and Hux Sr. are pretty much the complete opposite. Han is irresponsible at times while Hux Sr. is a millitary man. Han is a fun guy, Hux Sr. is rigid etc. So I could imagine it is a hellish situation knowing their sons are or about to get married to each other. So I want these two interacting whether it's AU or Not.
+++ It is said in the EU Han was in the Imperial Academy so Bonus if these two were there together and Met. +++++ Hux Sr. is a total dick to his Son, and at one point at the meeting of the dads Han sees this protects Hux Jr. Kylo of course...respects his father for it. +++++++ Han and Leia Declare they are adopting Hux Jr. after that.
