There's a great shot of the audience at the end of her LP - someone (not Orser) is by the rink absolutely leaping for joy - fist pumping, arms akimbo, overflowing with excitement. We often complain about Hamilton/Bezic's commentary, but how can you not smile a little at their enthusiasm.
That person leaping for joy like there's no tomorrow was Yuna's personal trainer who has been with her since 2008, I think. I understand he left his family in South Korea to stay full-time with Yuna in Canada. He would travel with Yuna to every single competition. Besides Orser and David Wilson, I think he's the other person who knows how great Yuna can be. And I can just imagine what was going through his mind while Yuna was nailing each and every element in that long program. I felt he was so proud of Yuna at that time, and he was so excited for her because she realized fully the greatness that she is capable of.
