There is a lot of Ji disengaging, and her eyes drift to the sides versus darting all around. Her hand gestures are very....delicate almost, but yet still rigid and sometimes firm, and fit perfectly with Fi hands (http://cognitivetype.boards.net/thread/707/fi-users-hands-examples-gifs)
I also used another video, as she seemed perhaps tired in the one you posted. (https://www.youtube.com/watch?v=a4rtxNo_mu0) She scowls, and uses her eyes very expressively, and there is at least one instance of the intense Se wide open eye signal as she uses it for emphasis. Her speaking voice reminds me of Enya's from the video on the main site, very gentle and unobtrusive, as an interesting possible parallel. To me FiSe seems likely, or at the very least Gamma.
