The Darth Maul cameo was arguably the biggest twist in Solo: A Star Wars Story, especially for folks who haven’t kept up with the tattooed Zabrak post-Phantom Menace.

Whether Han and Qi’ra reconcile or are further wedged apart, there’d be enough material to properly conclude their relationship.
So romantically speaking, Han and Qi’ra are toast, which is fine since we know who he ultimately ends up with in due time.
