"Route 666" continued . . .
I find this frame interesting because, although both Sam and Dean are using the mirror, Sam's is the only reflection we can see. It reminds me of the scene from Wendigo where Dean shows Haley Collins his fake ranger ID but the camera angle makes it look as though his arm belongs to Sam. It's just another one of those images that feed into the metaphorical theme that Sam and Dean are aspects of the same person.
Sam remarks that Dean and Cassie never look at each other at the same time: "You look at her when she's not looking, she checks you out when you look away."
LOL. I love that line 🤣
