Does anyone get the impression that at this point, or even from the beginning, that Nate just does the video part as an excuse to eat tons of food and go to the parks for free? Since he is single and doesn't really have any "Friends" aside from the other grifters in the park, it's like he uses the camera as his friend. That's why he also says "we" instead of me or I.
I honestly don't think he is a bad person like Josh, but it's getting pretty unhealthy, not just from a physical POV. I mean, if he did all the same stuff he does now, but did not film it, it would be perceived as a little creepy or just strange, and also a bit glutenous, but since it's recorded, it's not.
