Sophie Okonedo as Liz 10
Who doesn’t love the idea of the future descendent of the crown being black? Imagine all the “Well I nevers!” going on when that happened in “The Beast Below”! Liz 10 was awesome from the first time we saw her in that weird mask, and we loved seeing her again in a cameo at the end of the season. Might be a bit tricky for the Doctor to travel long term with royalty, but hey—these things can be worked out!
