Incidentally, speaking of all this talk of anime-only episodes,
from the rumour file, Moonphase is now reporting that episode 12 will be the
last episode in the TV broadcast, even though the DVDs have already confirmed that the show will have 13 episodes in all. So, if that pans out, that would mean that the show would have two bonus episodes; one in the middle of the series, on the third disc, and a second at the very end on the sixth disc. Personally, I'm not totally convinced of the rumour, but it is possible. I guess we'll wait and see...
