On the Ardatas theme thing, it isn’t a Vriska theme, I think? It’s breeding duties from genesis frog, which is more to do with Jade, her iguanas or Lofaf in general, but don’t quote me on who’s theme it is

Oh! I thought it was Vriska’s theme, but you’re right! The point still stands though, in that it’s not really a theme made FOR Ardata, so the Harpsichord use may be incidental. I’ve actually not checked it out in a while, I should do a big re-hearing of most of the Homestuck OST.
