Ah, that musical expression thing. Of all the things, Demyx definitely excelled at that. If only he did have a sitar. Unfortunately, the place they're at - grand as it is - doesn't sell those. He doesn't want to break it to Demyx like that, so instead, "Hey.. you want to get some ice cream? It'll probably make you feel a little better."

It always works with Roxas. Memories and all.
