The timestamped photo ids I received from Channing have been made available to clear any doubt that this interview was purposefully set up by Sam. I believe the male voice is James Price, another disgruntled MDE contributor who had been posting on Kiwi Farms with Channing.
James Price denies being the other person in the room. I had (probably) falsely assumed he was because Channing repeatedly mentioned bringing him on later.
