Lee isn't likely to survive. She's stuk in the middle of nowhere with no food and no knowledge of where to go. The water burping sound (don't know how to describe it properly) was a clear indication of another croc. I doubt the writers did that with any other purpose than to let us know that she would be killed eventually.
shareNo, I think it showed there wasn't anything there any longer inspite of her fear.
shareNot at all. She would have made her way without much difficulty back to the main river and by that time there may well have been an extensive search underway along the waterway for the boatman when he was discovered missing.
As for another crock, the likelihood of having two boat-tippers in the same locale is slim at best.
...then whoa, differences...
