Casandra 2-4 Sock Sprain - On my way to the train station - 14 min

Sarah is walking on her toes at her injured foot with aid of one crutch.
She has a black, red and grey sock on her foot but her ankle is still so swollen that she cant put on her ballerina shoe.
She jump on one leg down the stairs before she walk through a tunnel and jump on one leg up the stairs on the other side to the train station.
