"There's no way of telling what a cutie mark will look like before it appears, of course, though I'd hazard a guess that it would have something to do with her remarkable singing voice. She also has a gift for musical composition. Of course, nopony can simply be told what her natural talent is, she has to discover it for herself. It's the epiphany, the realization, that causes the mark to appear. But, rather than look inside to find out who she is and what she loves, she seems convinced that if she and her friends simply try enough random things that she'll simply stumble onto her special talent."
