I used to ship Ten/Rose, but then I watched season 8 and 9 and I fell in love with Missy and her relationship with the Doctor: after rewatching the previous episodes with The Master in season 3 and 4 I found myself enjoying Tensimm and Twissy far more than Ten/Rose. I still like this ship, but nothing and nobody will ever convince me that their bond is stronger than the one The Master and the Doctor have.
From The Witch’s Familiar, the Doctor saves Clara from the Dalek casing with Missy hinting about the Hybrid. It was a very heartfelt and tense moment of the episode, one I still get teary at whenever I watch. Both expressions on their faces were so sorrowful and full of anguish. :(
