The last thing he'll see as Donna as a Time Lord is a little sheep that's nudging a feathery hand. The Doctor holds it up to see nothing but feathers in it's place.

The flying birds get his attention and he watches them with a pair of wide eyes that are not his own.

He begins to fidget and soon his world is nothing but darkness when he shrinks into his clothes. There's a screeching sound and movement from inside of the clothing mound on the ground. He eventually frees himself and there standing in The Doctor's place stands one unhappy Horned Owl.
