Sorry if I wasn't clear. I didn't think he sat that way to look cool. I'm not going to re-visit old wounds, but I'll say it could also be because he has those enormous thunder thighs for doing quads.
I appreciate everyone's comments and posts. Thank you for addressing my question.
It didn't look to me like his Mom was with him for The Ice or Sun Valley. I didn't see his siblings in the Sun Valley videos and photos either.
re: social media, IG, tweets, oatmella, I don't know if it's entirely to do with his Mom's presence or absence. Some credit for the plentiful social media from The Ice must go to chaos enabler Dima Aliev. The Ice cast also includes other skaters he's known to be friendly with, especially Mariah. Mom was with him for both Heroes and Future and Dreams on Ice, and there was more content from Dreams on Ice.
In any event, we might as well enjoy while it lasts, because it'll be a different story very soon when he's swamped with school work and his usual training buddies aren't with him day to day. Thank you again, Romain and Mariah and Tony and Colin and Bolt and...
I just bought NBC sports gold figure skating pass. $60 for a year is not bad, you can also get $10 off with a coupon.
topic: who is that young boy in those videos? I saw the boy standing next to Boyang in two of the clips from yesterday, and once in that video which Raf was wondering how he ended up in Japan.. I agree with you, friends like Dima, Alina, Mariah and Mirai made the difference this time.
A friend forwarded me this code because she doesn't need it. I think it's on time use only.
Thank you as always for the information. If only Bolt were there too.
Speaking of which, is Masaru with Alina in Japan? Because as much as I love to see Nathan with his friends, I would be even more thrilled if Nathan could meet Masaru so we fans can have a cuddly pix (or even better, a video) to tide us over the long winter to come
Off topic,
I don't think Masaru traveled with Alina. Maybe someday Nathan will have the opportunity to meet her adorable and famous dog.
Hope Nathan will be ok at Yale without his study buddies - Bolt and Gizmo
bonita, I did forget Gizmo.skfan, you forgot about Mariah's bunny, Gizmo in your thank you note
Shame on me, when Nathan's the one who brought up Gizmo as yet another member of the Ponsart-Bell-Chen fam left behind in Cali. He's a good bunny uncle. No surprise, I think his sister Janice has a bunny herself. 
Nathan had his hair in a ponytail?!
Ok I think I see it now

Maybe time for a haircut for his ‘deadly mop’
I hope somebody reminded Nathan that the Yale Dining Halls do not cater to elite figure skaters, and he may have to figure out how to supplement the Yale meals, hopefully with something beside Red Bull and ramen. There's still enough time for the Olympic training center people to look over the planned meals (nutritional content) at Yale and advise him appropriately, right?
