Not to mention it's literally like...TWO clips of Luna we've seen in total*. And these clips are almost definitely taken from a singular scene. We don't know the context of this scene at all. Luna has not uttered a single word since we've seen her. Square has not focused on her yet for their marketing of the game.
The extrapolation is indeed beyond ridiculous and absurd.
*If I'm wrong on that exact number feel free to correct me, but I know we haven't seen more than a handful of shots of Luna in motion.
Nah, that's pretty much it. The only other information we've gotten from luna is
her escaping from the siege of Lucis on her lonesome and looking pretty ragged
