The best part of this episode, in which Race is held captive beneath a temple and replaced by a double by none other than Dr. Zin, is that no one really notices!
Granted, Jonny and Hadji have their suspicions, such as when "Race" shoots a snake and seems to enjoy it, but the real hero of this episode is Jade.
She joins in on the mission just in time, and leads the phony Race outside where she proceeds to kiss him (very racy for the time, I'm sure) and then pronounces that he is not Race.
When the boys ask her at the end of the episode how she could tell, she says, "There's only one Race Bannon." Got that right! Guess there are some things Zin just can't teach his clones to immitate!
