It happened again, Kris left Tao alone, and he got lost again. This time its worst than the airport incident.
Read this first, to understand the references to the other incident.
Based on that Disney fancam . Kris (and the whole group) left Tao while he was trying to look at merchandise.
That nice group of fans had to yell out that they forgot someone. And even then Tao couldn't catch up with the group.
It's also set a little bit after that incident, in the parking lot and the hotel.
