Again, this might have been because of all the noise in the house, but was it established that Donna's head is now safe and will no longer explode, or was it just back to possible-explodey-square-one? It's like Rusty handwaves all these things and it's all IT'S OKAY NOW, WE GLOVED THE PEOPLE BACK INTO HUMANS, and I get really lost as to what happened and why. I hate his fucking quick resolutions.
