Is that a last-page reveal (it looks like a last-page reveal)? Because that reads as the classic 1980's scoundrel/con-artist "marriage" reveal. Folks need to remember how often the plot of sitcoms or movies thirty years ago involved scam marriages to get things like green cards or inheritances. Revealing that Han, in his pre-Rebel smuggler days was technically married doesn't mean that he was involved in a relationship, but rather (in the sort of storytelling that STAR WARS stems from) means that we're in for a con-gone-wrong that he either forgot or tried to forget and that a certain woman now won't let him forget...
