Every living being is always bound by a choice that determines their destiny. For example, when someone is faced with two different paths, what will they choose—left or right? And what will they find when they decide?

That's also what happens with Maeve's ability when encountering various choices; she will first choose the first route.

After she finishes, Maeve realises that the route is complex; the woman returns to the starting point of her intention to create a previous time flow that we can call route x.

On the second try, she chooses the second route; when she reaches the end, she decides to return to her choice, which makes it route y. The woman keeps trying and creates a route y. She continues to try and create another route until it becomes route z.
