I agree that 8x11 was probably the best episode of the series, even though the Quinn/Katie thing was way over the top for my taste. Katie was good,. Quinn? Not so much.
While I don't really agree that it was worthy of an Emmy, it's One Tree Hill after all, I did think it was a lot better then 3x16, because that episode was just...blah. Certain things were good, but a few lines here and there kind of ruined it for me.
