We see Castgirl crutch with her sprained right ankle in a white sock on her way to the trainstation.
In the next part, Castgirl is on her way up from the platform after taking the train to Copenhagen.
She stops and lets the other passengers go up the escalator before crutching it herself.
We get a close-up of Castgirl's injured foot and you can see how swollen it is even though she is wearing a sock.
