Two months after Father Octavian recovered from his injuries, he was ordered to retrieve one of the deadliest aliens known to mankind, a Weeping Angel, from the star ship, the Byzantium, which crashed on the planet Alfava Metraxis. It was arranged that Dr. River Song, while serving a prison term at the Storm Cage Holding Facility, would join Father Octavian's team of military clerics on the covert operation.
River Song sent a message to the Doctor from the 51st Century. The message was engraved in Old High Gallifreyan on the side of a flight recorder from the star ship Byzantium. Once The Doctor discovered the recorder, he took the TARDIS to rescue River from the Byzantium before the star ship crashed on the planet.
Once the TARDIS landed on Alfava Metraxis, River provided the coordinates to her ship orbiting above. Moments later, as Father Octavian, Bob, Christian and Angelo materialized on the planet, the Doctor realized he was glad to see the military clerics once again. He had been waiting for this moment for a very long time.
Father Octavian walked up to River Song and said. "You promised me an army, Dr. Song."
River smiled. "No, I promised you the equivalent of an army. This is the Doctor."
The Doctor smiled and saluted.
"It's an honor to finally meet you, Doctor," Father Octavian said. "I want to thank you for what you did for me and my men during the Churchill incident."
"I was glad I was able to help. I'm sorry about the two men you lost," the Doctor said.
"Thank you. Now, has Dr. Song explained what we're dealing with here?" Father Octavian asked.
"Doctor, what do you know about the Weeping Angels?" River asked, smiling.
The thought of the Weeping Angels sent a chill down the Doctor's spine. They were one of the deadliest alien species he had ever encountered. Father Octavian explained that their mission was to recapture the Weeping Angel trapped inside the Byzantium and neutralize it before it became too powerful from the radiation leaking from the star ship. The Doctor realized this was not going to be an easy task and he had to be extra cautious, with no distractions, especially from Amy and River.
As the clerics set up base camp, River walked up to Father Octavian. "I've been meaning to ask you, what happened to the cleric, David?"
A look of confusion crossed Father Octavian's face for moment. "Oh, that's right, you've met him." Father Octavian said and smiled. "He left the service of the church and married the love of his life. Her name is Socorro. Last I heard they're adopting twin girls."
"That is marvelous news," River said, smiling. "I knew he was special the moment I saw him. I'm glad everything's worked out for him."
"As am I. Thank you for asking. Now, please excuse me, Miss Song, I have matters to attend to," Father Octavian said and left.
"Yes, of course," River said as she watched the priest walk off.
Two hours later the group was inside the Maze of the Dead, the stone labyrinth which contained numerous statues. As the group explored the first level of the Maze, Bob opened fire on one of the statutes. Apologizing profusely, Bob tried to explain that he had seen one of the statues move.
"We know what the Angel looks like. Is that the Angel?" Father asked Bob irritably.
"No, Sir."
"That's right, it does not. The Doctor has told us we are facing an enemy of unknowable power and infinite evil, so it would be very good if we could all remain calm," Father Octavian said harshly.
"Yes, Sir. I'm sorry, Sir," Bob said remorsefully.
The Doctor walked up to Bob and Father Octavian. "Well, Sacred Bob, Scared Bob, fear keeps you on your toes, it keeps you fast. It'll save your life one day."
"Yes, Sir," Bob said, smiling at the Doctor. Bob looked at Father Octavian and was surprised to see a smile on the Bishop's face.
"Try not to kill any more stone statues," Father Octavian said to Bob and walked off.
The Doctor chuckled, patted Bob on the back and went to investigate the statue Bob had fired upon.
As the group was ready to progress to the second level of the labyrinth, Father Octavian ordered Christian and Angelo to guard the entrance to the Maze, but something didn't feel right; something was nagging at him in the back of his mind.
"Belay that order, Christian. I want you and Angelo to secure the exterior of the ship. I do not want anything or anyone interfering with our mission. Keep an open channel at all times…and take Bob with you," Father Octavian ordered.
"Yes, Sir," Christian said as he led Angelo and Bob out of the Maze of the Dead.
While the group continued their journey through the fourth level of the Maze of the Dead, River felt there was something wrong about the statues but she couldn't figure out what exactly.
"Doctor, there's something…I don't know what it is," River said.
"I agree, there's something. I'm working on it," the Doctor replied.
A few yards deeper into the chamber River and the Doctor recognized the problem simultaneously but it was too late. The Doctor had led the group into an extremely dangerous situation – the statues in the Maze were actually Weeping Angels and the group was surrounded by them.
"Father Octavian, there's no time to waste. We have to get out of here, now!" the Doctor said.
"What? What's going on?" Father Octavian asked, alarmed.
"I'm sorry, but all the statues in this labyrinth are actually Weeping Angels!"
"Dear God!" Father Octavian exclaimed.
"Exactly! I believe these Angels are weak only because they haven't had anyone to consume over the centuries but they're becoming stronger now that they're absorbing the radiation from the ship. The Angel on the ship must have crashed the spaceship to rescue these Angels," the Doctor said.
As the group tried to escape, the Weeping Angels lured them to the highest point of the Maze, and trapped them directly under the Byzantium where they planned to kill them.
