"How are you here? I thought you said both dimensions would collapse if you ever tried to come back here." Rose asked as she handed out their tea, still wiping overjoyed tears out of her eyes.
"That's the problem, actually, I have no idea how this could have possibly happened, because you are absolutely right. We shouldn't even exist, and that's what bothered me at first." He felt around in his pockets for the shard.
"At first?" Amy and Rose said in unison. Rose laughed, but Amy avoided eye contact with her. She had never seen the Doctor act that way with anyone, and he'd never even mentioned Rose…that night when she'd wanted so badly to be with him…everything about his reaction to her made perfect sense now.
"Right, at first, but now I more or less understand what's happened here." He held shard up for them to see, this time using his jacket.
"That shard? That's why we're here?"
"Yes Amy this is exactly why we're here."
"A shard? Of what?" Rose asked, leaning closer.
"This is a shard of a weeping angel,"
"Which still doesn't make sense, since they were sucked into non-existence right in front of us. " Amy added, annoyed.
"Let me finish. This is a shard of an angel, but not the angels we've encountered. This angel is different, it's special."
"But why?" Rose touched his shoulder. Amy gagged quietly.
"Because this particular angel, what's left of it anyway, is giving off heavy Dalek energy as well as its own." Amy and Rose watched intensely as the Doctor once again donned the glasses.
"And it is covered in void stuff, neither of which surprise me. Void stuff is a general substance, clinging to anyone who has ever passed through the void. Therefore one should expect that the void stuff surrounding any given person will absorb they're specific energy. What's fascinating about this little piece of stone is that the Dalek energy emanating from it is not radiating from the void stuff surrounding it. It is actually being produced by the stone itself."
"So, what then, the Daleks created their own angel?" Rose inquired. The Doctor paused and his face lit up.
"Of course, the Dalek's created their own angel! But why? The angels are gone, they never existed, so I suppose that's what makes it so attractive an ambition, but why target Amy and I? Why send us here?" He though for a moment, pacing. The truth dawned on Amy so suddenly that she gasped, drawing the Doctor and Rose's attention.
"They want to keep us…you here. You said it yourself, you can't travel between these two dimensions without everything being ripped apart, and even if you wanted to…we don't have the Tardis, they do."
"And if the angel is their own creation and wasn't sucked into the void," Rose added.
"Then that means that…we were set up to find this shard." The Doctor scowled at the small piece of rock in his hand.
"That's how they snuck up on us. They knew I'd be interested in what they'd done," The Doctor slammed his hand down on the table in frustration. It wasn't like him to walk so unaware into a trap, and he despised that they had managed to catch him off guard. He wrapped up the shard in a tissue and slipped it into his pocket.
"So what do we do?" Amy asked, finally feeling as though they were getting somewhere. The Doctor paced while he thought, which made both Rose and Amy restless. After an agonizing minute of watching him struggle for an answer, Rose got up and gently took his face in her hands. Amy looked away, angry and slightly humiliated.
"Doctor," she looked into his eyes, trying to communicate with him internally to relax. He sighed and took both her hands and held them, looking down. He was still for a moment, then looked up, an epiphany bright in his eyes. He looked at Rose and Amy reassuringly.
"We need to find Donna."
