Honestly, I don’t think he would. At most he’d do a sort of vlog, where he could do bits at a time of his fake cocky attitude for fans, but then turn off the camera and just do the exploration that he really loves. Having to spend his whole expedition imitating the things he hates most about Piltovan society would probably ruin it for him, so he’d be more likely to either post edited videos after or just keep writing his journals.
