Hahahah that's sort of how I have her too! She's 1998 Slytherin, and originally Marcus was like lol no when she wanted to try out in her earlier years. After he graduated, the ~ban eventually went away and she made the team. She always worked harder to prove everyone wrong and became competitive to keep her spot on the team, etc. Basically, if someone tells her she can't do something (for whatever reason) she's like FU YES I CAN.
