Donna Six cringed and scrambled back. Something in her flickered, a moment where she started to blur — but a moment later she was back to herself, still somehow in one piece. Perhaps she didn't have it in her again to split, perhaps she was doing her best to keep it together. She covered her head in her hands and ducked, making herself small and huddling up against the wall. Heart pounding, she couldn't breathe, she couldn't breathe—
"No?" Donna Five snorted with derision. She kept the gun trained on Six. "And what do you know about 'the way', Doctor? You need someone to hold you back. You need someone with you to keep other people safe. Is it because I've got a gun that suddenly you're squeamish? Is that it? Or is it because you don't get a flipping say in this? You'll make decisions for everyone else — you think you're better than everyone else, that you have some sort of high ground, some sort of authority, but what are you, really? You're a liar. Your TARDIS chews up people and spits them back out. Have any of your girls had a good end?"
