Oh, I love that! Look at Gabriel at the end of “Adoration” in the shot where we see him from the outside in Marinette’s POV:
He stands there in a way that we the audience recognize as a visual reference to his Monarque transformation pose and the shadows create a butterfly-like form. The black space between Gabriel’s legs and right under his hands, which are also in a visually similar position again, create the illusion of his staff.
Plus the shadow over Gabriel’s chest leads your eyes right to his tie where of course his Butterfly miraculous is hidden.
But the most interesting I find Gabriel’s hands in combination with the shadows and details of the french bacony (so..regualr balcony in this case? lol). It’s an optical trick depending on you remembering how his hands look like in the transformation pose so your mind makes sense out of the kinda visual mess that doesn’t properly check out when we see him standing there. From afar it looks like Gabriel is once again laying his right hand (with the wedding ring) on top of his left one - as per usual. But when you look closer, that’s not the case: Gabriel’s left hand is on top of his right, which is of course what he has to do to control Adrien with the amok object in this very scene.
All Gabriel is doing is holding his hands in a way that doesn’t make it obvious.
And to really drive that point home, right afterwards after Marinette left we see Gabriel holding his hands in front of his chest:
Reminding us which hand the ring is on and what he obviously has been doing just now.
