In the end, when he decides to stay, he meets the alternate version of his wife again and they strike up a friendship, leaving him hopeful that they may get together in the future.
- For Want of a Nail: This is explored through the lives of three Alternate Universe versions of Mason Stark. The lives of the clinically depressed former Eigenphase Industries project manager Mason and the more confident Eigenphase CEO Mason diverged when they were fifteen years old and they each arrived home late and got into an argument with their alcoholic fathers, who started beating them. In the project manager Mason's universe, he let his father beat him instead of fighting back as otherwise he would have beaten his mother again. In the CEO Mason's universe, he fought back and was able to stop him. As a result, his father entered detox and successfully turned his life around. The CEO Mason's life improved considerably as a consequence of this, allowing him to develop greater self-confidence. Unlike the project manager Mason, he finished graduate school and slowly worked his way up the corporate ladder at Eigenphase. The killer Mason's life followed an almost identical path to the project manager Mason's but the former shot most of the people in his office while the latter only considered doing so briefly, quickly realizing that he could never go through with it. The project manager was about to shoot himself when he was brought to the CEO's universe.
