Marina's dislocated knee
From the archives of TiPWiki, the unofficial Duke TIP Wiki
During Rice 2019 Term 1, Marina, a 3rd year in Cat's group fell and dislocated her right knee during the last dance at around 8:30, and had to go to the ER and missed the tradition dances. She was at the ER until 4, when she came back and Cat wheeled her around the 4th floor in an office chair.
