Sorry, I didn't think I needed to break it down . i didn't mean are they married, I'm curious why she keeps calling him that. She doesn't really have a sense of humor. They are not together
It was just to remind viewers that, in the eyes of The League, they are husband and wife since that came into play during the duel scene.
That scene, by the way, fell pretty flat for me. Not only was the fight between Malcolm and Ollie far too brief, but the way some of the lines were delivered, it really felt like the two were conspiring against Nyssa. The other scenes between Barrowman and Amell, however, were extremely well done.
