I was struck by the similarity between the windows in the old distillery and the wheelwright’s workshop. Colorful in the distillery, black and white where the angels have taken Cas to torture him and mess with his programming. Reminds me of the punchcard-esque motif in Naomi’s office.
We know from the psychic in 10×17 that Cas’s very nature is colors. The angel minions’ black and white ties (rather similar to the stunt demons’), the windows, and the black hood all emphasize that they’ll be attempting yet another assault on Cas in the name of punishment and correction.
Also look at those old caged halo lights in the background – they’ve been associated with him for a looong time. Especially to symbolise when he’s trapped and controlled: 4×21 was huge on them.
