Some didn't fully understand this one. So let me explain. This is CGI of a really good mask. The whole thing is fake. It's a multilayered illusion. Similar to what you are seeing in DC at times. In other words, yes Bidan really wears a mask, but there are times where you see CGI mask Bidan too that never really exists. It's a multilayered illusion. An example would be Bidan skipping steps on Marine 1. Yesterday plane really took off from DC to Delaware yesterday but that doesn't mean he was on it. They can make him appear in Mexico in an hour drinking tequilas on the beach.
Learn to "see" it by paying close attention and discernment. Once you get that awareness, you wont be able to "unsee" whenever this happens.
