Oh, I love the UNIT family. I'm hoping we get a new one with Martha and Colonel Mace and the Captain that kissed him whose name I can't recall.

True, Jenny could calm him down a bit and she did challenge him, and I think RTD has actually proven that the Doctor can have character development so it could happen. I'm not completely against the idea, I would have to see them in action together without Donna before I could really get behind the idea like I see many in fandom doing.
