"You did? Really?" The Doctor blinked, nonplussed. How had he missed that? He supposed he'd never asked. When Rose had returned, he hadn't had a thought in his head save her. That was how he ended up with two of him in the first place. That was how she'd been left behind in another dimension with a man who was him and yet not him. Now that she was here to show him the path that he'd walked, he could see the series of mistakes and the sheer arrogance inherent in his thinking. He was the Doctor. He made people better. Except he wasn't perfect. Far from it. Davros had been right. No matter how good his intentions, he left chaos and destruction in his wake. He never stopped running because he was too afraid.
"Anyway. Lucifer. Satan. Whatever you want to call him. I thought we already did this one. Or I suppose maybe we haven't." He tugged at an ear, finding that the longer they sat, the harder it was becoming to keep still. "The Beast might have been something completely different. Or there might be more than one. Different source for the legend in each particular universe. I'm guessing no one's left us a convenient black hole, have they?"
In truth, he wasn't certain he could handle the Beast again. Not now. Not so soon after losing his people for a second time. His hands were shaking. Shock, he reasoned. A delayed reaction to everything that he'd been through, triggered by the news that more was coming, and yet again he'd been asked to face hell. He crossed his arms in front of him, fingers wrapped around his elbows to still the tremors, and leaned forward to rest his weight against his knees in an attempt to conceal the evidence that something was wrong.
