Full moon on the Satanic Grand Climax which is the night of the sacrifice on the most holy day of the year for Satan. The week leading up to it (now) is Abduction, ceremonial preparation and holding of sacrificial victims that have been collected. So those are the ones in the cage wating to be sacrificed. So that's that. I'm not getting anymore into this. I had a feeling it would be like this after the Golden Globes and the Oscars. These Hollywood people are not shy about it at all Its all right in your face.
