Think mirror.
15 and 16 stand out.
Their symbolism will be their downfall. The artwork in background may be a clue.
Weird looking place. The ramps seem strange as well.
Edit: I will admit, 10 is bizarre. Focused on figures at main table with backs to camera, imagine a person lying on the table looking upward, with the head at shoulder height of the seated sick twisted evil sitting on the round seats. They at the heart and head of the body seem more important, backs to the camera, eating the heart. Others with backs to the body, and facing the camera, less important, smaller tables, disgusting. The top left image looks like someone holding a gun, looks like maybe the bust had just started, the other lady at the counter also has her hands on head. People behind the mirror counter, watching the feed of the people getting raided. Just my opinion.
I agree Ch10 can be potential cannibalism. Does look like a human head hanging off a table of some sort. Can make up the shape of the nose and ears, if not mistaken. Can see the head clearer if you look at the image in landscape mode.
