Doctor Who: The Planet of the Ood
The funny Donna season is not supposed to make me tear up every single episode.
Absolutely loved this. I love that the Ood actually had everything well in hand -- it was a chance for the Doctor to see that the universe doesn't always lean all of its weight on him, that other people and other species can pick up the slack and save themselves.
Once again, there's that damnable hope rising up. What does the Doctor's song ending mean? And they played his song, the one that means his home and his nature (the one that was interwoved into the sounds that represented Rose's determination, and we heard that part of the Doomsday good-bye song again in Partners in Crime -- the two elements are still separated, for now). He's allowed to share in the joy of freeing the Ood and hearing their song.
Donna hearing the full weight and pain of the Ood's captivity -- seeing the horror of the Doctor's world and longing to back away, as she did in The Runaway Bride. This was supposed to be her holiday and she's seen a city burn, a species in captivity, and dozens of people (human and Ood) killed. But she's also seen grace and new beginnings. Which burns stronger for her right now -- the wonder or the horror?
