I love how serious and dramatic he is in the video, starting from the very beginning, where he walks down slowly from the stairs.
He feels so serious and ceremonial, that it almost seems like a mask, then randomly bursts out laughing.
His story about how he dealt with his broken tooth (around 2:35), doing the exact opposite as what people usually say to do (drink warm water), and drinking ice cold soda, and eating intense food instead to deal with the pain, also maybe how he and his staff is doing snowboarding for 7 hours, in a serious and competitive manner, not really as a leisurely activity might point to Si PoLR? Although this could be because of many other things.
Then (5:40) he talks about how he is taking singing karaoke seriously, because "there is at least one other person at there, and being able to move people by singing is what qualifies you as a singer - and I think that your worth is based on how much you can make them cry."
Not a super serious analysis, but you mentioned EIE, and I could see him as one too.
