We see Sarah come crutching with a big white sock over her medical SLC at the train station.
She takes the escalator up to the square outside the theater where a performance has just ended, which means there are a lot of people.
We see her crutch up a long stair before the first scene ends.
In the next scene we see her refueling the car and get a close-up of her cast and painted toes.
