There has been a lot of discussion recently about the Dharma Booth Video, and why Daniel is the voice of the cameraman when he has just died. After watching The Variable, I have come to the conclusion that I actually think the cameraman is Miles.
I would recommend listening to the video again, but this time picture Miles saying everything the cameraman says. Personally, I think the majority does sound more like him than Daniel, particularly at around 2:35 when he says 'None of that matters!'
It also completely fits with the storyline of the events that occurred in The Variable. The last time we see Miles in that episode is when he hands the keys over to Daniel, and from then on, he is nowhere to be found. My theory is that this could be the last time Miles will see his father, so he pays him a visit at his home (we know Pierre is at his home from Radzinsky). He admits that he is his son, and he proves it by telling personal family things no one else would know. This is why Pierre in the video says that is source is credible, because it is his own son. Miles tells Pierre about the future in 30 years time, and then for whatever reason they decide to make a video about it.
What do you think?
