The climb up the levels was long. The higher they got the more Aderyn wished she had gone back to the TARDIS. Something didn't feel right. But she couldn't quite pinpoint what it was.
"Isn't there a chance this lot's just going to collapse? There's a whole ship up there." Amy asked.
"Incredible builders the Aplans. Had dinner with the Chief Architect once. Two heads are better then one."
"You helped him?" Aderyn asked.
"No I mean he had two heads. That book at the very end, what did it say?" The Doctor said. River shone her torch over Aderyn's shoulder.
Aderyn had kept the book close to hand. She now flipped it open.
"Read it to me."
"What if we had ideas that could think for themselves? What if one day our dreams no longer needed us? When these things occur and are held to be true, the time will be upon us. The time of Angels." Aderyn read.
The Doctor stopped walking for a second. His own thoughts taking over once again.
"Let's move." He said eventually.
"Are we nearly there yet?" Amy asked "It's one hell of a climb."
"Only two levels to go." River said.
"Lovely species the Aplans. Very relaxed, sort of cheerful. Well, that's having two heads, of course. You're never short of a snog with an extra head." The Doctor said cheerfully. He reached out and grabbed the back of Aderyn's shirt, pulling her back before she could get ahead of him.
They kept climbing. Something was bothering River. It was something the Doctor had mentioned that just didn't sit right. There was something wrong but she couldn't put her finger on it.
Aderyn broke away from the Doctor and hung back to speak to River.
"something isn't right," She whispered "I don't know what it is."
"I know. There is something." River said. She put a comforting arm around Aderyn. She could feel Aderyn's heart beating quickly.
They had almost reached the top level when it happened, when they finally realised what was wrong.
Aderyn, having caught up with the Doctor, stopped in her tracks, the light from her torch landing on the head of one of the statues.
"Doctor!" She called.
"Come along Aderyn, lets not linger." The Doctor replied.
"But Doctor, something isn't right with this."
He walked back to her, looking up at the statue she was staring at with horror. "Oh." he said.
River and Amy walked over to them, the clerics stood around looking confused.
"Oh," River said "how could we not have noticed?"
"Low level perception filter. Or we're really thick," The Doctor shone his torch around the chamber before finding an alcove. "Everyone over there," he shouted, ushering Amy and Aderyn ahead of the clerics. Soon they were all back against the wall. The torch light fell on the statues.
"What's the problem?" Amy asked.
"The Aplans." The Doctor replied.
"The Aplans?" Father Octavian turned to him "But the Aplans are dead."
"The Aplans had two heads. So why don't the statues?" Came Aderyn's voice from somewhere behind River.
"Right everyone turn off your torches," the torches went out. The Doctor kept his focused on the statue Aderyn had been staring at. "I'm going to switch this one off too, just for a moment."
And he did. When he switched the torch on again the statue had turned to face them.
He ran back they way they had just come, looking out over a wall.
All of the statues they had passed had moved. They were coming towards them, arms outstretched.
"Bishop, I am truly sorry. I've made a mistake and we are all in terrible danger. Every statue in this Maze, every single one, is a Weeping Angel. They're coming after us." The Doctor said, running back to the group.
