As promised, you all know that story of a scorpion and a frog. Forgive my fuzzy memory but in that story, a river was full and the scorpion couldn't cross it yet the frog could. The only way for the scorpion to cross was on the frogs back. While the frog was well aware of the scorpions sting he was still willing to help him hoping that since he was helping the scorpion, he was wasn't going to sting him. Well, when they got in the middle of the river the scorpion stung the frog to death and guess what? They both drowned.
Probably not the same story you read but you know, literature with translation and stuff. Anyway, in this story you can already guess who Tina is and who Audrey is.
