Continuity mistake: After Johns dies and Riddick is talking to Fry you see in one shot that only the bottle that Fry is holding is lit up, yet in the very next shot you see that all three, Fry, Jack, and the Muslim kid's bottles are lit. (01:23:40)
Richard B. Riddick: Not for me! Not for me.
Question: When Riddick says that the monsters can track them because the girl is bleeding, and Jack is revealed to be a girl, is it her period that he is talking about? Did Riddick smell it, too?
Answer: Yes, it is her period. Considering that he lived in darkness for years, it's possible that he smells it too. It's also equally likely he realized she was a girl and that the creatures were all riled up and put two and two together. But the first explanation fits Riddick's character better.
