I thought Harold would still be childlike, so he surprised me by recalling how he can remember the doors passkey, and then he scared me.
To me, it was obvious that Gao knows how to fight truth serum, but I don't remember any mention of her age before.
I still want to know what her role with the hand is, about her as the Triad leader, and how come she didn't push Danny by the end of episode 8 like she pushed him in a previous episode, and pushed Matt before near the end of season 1.
I was hoping they'd do the chi of healing trick, it's fun to look at.
