You have challenged Morgana to hold her breath as long as she can. She brags at how well of a swimmer she is and takes on your challenge. She starts holding her breath standing up and starts to beg you to let her breathe. You allow her to. She sits down and holds her breath again until you say ok. Then she lays down and struggles even more to hold her breath until you allow her to again. By the end, she's really embarrassed at how out of practice she is and you end up winning the challenge!
