Chan invites Caine to participate in the tournament to repay a debt he feels is owed as a result of the events in ' Challenge '.
Caine: If you are given everything, you have nothing.
Peter: What is Chan doing here?
Caine: He is not our enemy this time.
Peter: I'd rather have a snake for an ally.
Caine: Hatred has destroyed your soul, Li Sung. You are already dead.
Frank: As long as you maintain harmony, innocence, sincerity and honesty, the tiger will not bite but challenge it and you risk its' fangs.
Peter: (to Caine) You know, every time you start talking in riddles, I know that you're into something dangerous!
Strenlich: (to Peter) Your dad has a way of getting into people's heads.
