In refer of the first case, the brothers, I thought that thirsty brother was healthy. For this reason he was thirsty and her brother will have any problem in your heart. For this reason he wasn't thirsty. Few minutes after he was drank, he died.
The second case, I don't know why the wife's traveler was so quiet. I don't knew that the film was recorded. I thought that she was watching television on line emision. Sorry, I didn't think of anything.
