 Hawking takes Desmond on a walk, and Hawking notes a particular man, with red shoes, just before he is crushed to death by a falling scaffolding.She explains that although she knew the man would die, she did not help because the universe has a way of "course correcting", and he would die anyway; if she warned him of the scaffolding, he would be hit by a taxi the next day, if she warned him of that he'd break his neck in a shower accident the next.Desmond and Penny go on a walk together and take a picture, where he breaks up with her after realizing that he does not have enough money to support her.
