A Theory on DougieCoop's Appearance
No one in Vegas recognizes that Dougie has been replaced by Coop. Not even Janey-E or the doctor who examined him in this episode. The Doctor even complements DougieCoop for losing a lot of weight.
Is it possible that when people saw DougieCoop, they didn't see him as Coop, but they were still seeing the real Dougie even though his body's been replaced by him? Only us the viewers could see Dougie as Coop, but Janey-E and everyone in Vegas who interacts with him still view him as he's Dougie. Perhaps only Sonny Jim knows the truth, but he isn't talking 🙂
I'd love to see DougieCoop standing and looking himself in a mirror to confirm this theory.
I don't remember which part it was, but there's a scene in Dougie's house where Cooper stands and front of a bathroom mirror and looks at himself very intently, and there doesn't seem to be anything amiss with his reflection.
It doesn't seem possible that anyone was seeing him as Dougie because Jade, Bill Shaker, Janey-E and everyone Dougie works with have commented on "Dougie's" loss of weight and/or new hairstyle.
I'm with Clay, he saw himself in the mirror and maybe I missed something, but it was just his reflection as Coop. And Jade recognized his new suit and hair, "have you been wearing a rug all this time?" The guy at the casino recognized he'd lost weight and got a new haircut, too. Janey-E asked where'd you get that black suit and that haircut. People have repeatedly noticed at least those 3 things, weight, haircut, suit.
There seems to be so much cognitive dissonance, though, that they don't get more suspicious.
