The Donna closest to him looked sharply over her shoulder.
"Are we?" she asked, sarcasm dripping from her tone. "Are we, though, because I just saw ten of us appear and drop flat because this one can't keep calm."
They might have been wearing the same clothes, but they were different. There was something dark about the one who stood next to the Doctor now, something cold in her eyes that made her look very unlike Donna Noble at all. She had the same hair, the same face, the same voice, but despite that, she hardly looked like the woman that had once been the Doctor's very best friend.
The one further down the hall, however, wore an expression that the Doctor knew well. It was that same panicked, searching expression that she'd had on her face the day that the Doctor had to erase her memory — eyes wide, tears welling up as she scrambled back.
"Don't let her near me!" said Donna Six, who didn't feel like a Six at all. Seeing the Doctor now made her wonder, briefly, if he ever felt like a Twelve. It was him, but it wasn't, and Donna hadn't yet decided what to make of him.
The other Donna reached into the waistband of her jeans. For a moment, Donna Six squinted at her with confusion — until Donna Five raised her hand, tightly closed around the grip of a pistol. Plenty of people carried them around like they were nothing. Nicking one hadn't been hard.
"Never did like these much, did you?" said Donna Five to the Doctor, a snide little lilt in her voice. "You always said that this won't solve anything. You know what? I think it will, today."
