Maybe it involves the characters reminiscing about their time at Beacon Academy. They could think about the classes they took, the friends they made outside their teams. Like Weiss remembering her struggles with fitting in among students from different backgrounds, and how those experiences shaped her.
Another plot could be about the characters thinking back on their relationships with their families. Yang might talk about her search for her mother, and how her memories of her father influenced her journey. This could add a lot of depth to the story as they realize how much their family has affected their present selves.
