What if the Doctor meeting Donna was in the wrong order, like with River? What if Donna doesn't remember all these huge events that had occurred because the Doctor took away all her memories of him and the weird things that had happened.
Quite possibly my favorite scene with Doctor Donna =) I love her because for the first time 10 can have a companion who isn't falling in love with him. It took me a while to get over Rose Tyler but I really loved Donna Noble
wait i always just assumed they knew each other! so the show just happened to cast the two of them and they just happened to be cousins? im sorry thats just crazy! --- Doctor Who is crazy. Amy and little Amy are cousins
