While Ten and Rose may be my favorite pairing, Donna will always be my favorite companion. I have the utmost respect for her and her story breaks my heart. The fact that she grew so much throughout her time with the Doctor only to have to go back without having a clue about how truly important and vital a person she is. Never think you are not worthwhile. Just because you may be stuck, does not mean you don’t have the potential to make a difference. We may not all have the Doctor in our lives, but we can all do things to make a difference.
