Oh, lovely. You really have the Doctor's voice nailed, and I love your alt!Donna. I'm really glad to see more of her! I love, especially, that she catches on to the sadness behind the Doctor's eccentricity and draws the conclusions that she does. That just feels very right to me, very in tune with the Donna we saw in TRB, who might have been shouty and self-centered but who also didn't want to see people hurt and in the end was willing to step in front of the Doctor to protect him from the Racnoss. She might not see the bigger picture all the time, but she has a real knack for the details. Looking forward to the next chapter!
