Something I forgot to mention in my post about The Mark of the Rani: I was surprised to hear The Rani remark how she is able to change faces with ease as oppose to how The Doctor is stuck with his. Granted, she's ribbing him about The Sixth Doctor's colorful appearance but The Doctor doesn't push back on the comment, which makes me think that's something The Rani is actually capable of doing. It's worth noting how Romana was able to change bodies with ease, too. Maybe it's a Time Lady trait or The Doctor has some inability to change like they do without death's help.
I'm surprised that I don't recall this conversation from my previous viewing since it's the kind of thing I've always been fascinated by (anything Time Lord society has my interest). Either way, I wonder if that's something that'll come up in the final two episodes, especially since she has two bodies now.
