You should overlay this video on top of the 3 Elizabeth L. videos from the 1st 3 sequences. I think there are going to be more of these videos to come. Sounds like a message was embedded in the video. i think they are using the Superlumina/Echo method to send the message, We’re not seeing the whole message cause it is echoing; one echo to each video. After all the echos get to us and are combined we should see the whole message.
