Gaia was aware her sister could and liked to sing, it'd been one of the hobbies their mama had introduced to them as a choice of taking. Gaia herself had refused to do any of them, play an instrument, singing or dancing. Nia however had taken singing lessons and the time they shared their room the Gryffindor would sing a lot. Taking place in the audience Gaia didn't mind the first performer, Lucy, she was good but she was really only here to support her sister. As Nia stepped into view she could tell her sister was nervous, but eventually she found her voice and grew more comfortable earning a small smile from the Slytherin herself. After Nia and her friend Angelo were done, Gaia clapped and watched the rest just to be polite, while sketching in her sketchbook.
