The glass case was starting to break as the mummy kept banging on it. At the same time, the asteroid shook beneath them. Merry cringed and held onto Dean's hand tighter. Dean curled over her protectively. The Doctor started pushing them towards the door before a bone-chilling noise echoed through the chamber.

"What was that?" The Doctor whispered as three cloaked creatures appeared behind them.

Merry gulped. "The Vigil." She said, unmoving. "They're supposed to feed me to Grandfather if I am unwilling."

"Merry…" They growled as they stepped closer.

The Doctor pulled out his screwdriver and pointed it at the creatures. "Stay back! I'm armed!" The creatures stopped and tilted their heads. The Doctor turned on his screwdriver.

Unfazed, the Vigil extended their hands and released a wave of sonic energy. Dean and the Doctor flew backwards into the walls. The Vigil stepped forward and gripped Merry's arms, moving her closer to the mummy.

Dean struggled to get up. To get to Merry. He won't let her die. Not anyone. Not again.

"Dean!" The Doctor shouted at him, crashing him back into reality. He pointed to the screwdriver. "Give it to me!"

Dean grabbed the screwdriver and threw it to the Doctor. The thing whirred to life as he used it to repel the Vigil. Merry scurried away from them, running to Dean. Dean stepped over her, putting himself between her and the Vigil.

"Merry," Dean said, half turning toward her. "Is there anyway we can get out of here?"

Merry closed her eyes in thought. She was shaking violently before she opened her eyes and sang a few notes. Behind them, a wall opened.

Dean grabbed Merry's hand before charging towards the open wall. He led her outside before going back in to get the Doctor. He was still kneeling, pointing his screwdriver at the Vigil.

"Doc!" He shouted. "Come on! We gotta move!"

The Doctor glanced at him before dropping his hand and running over to the opening. Dean ran out after him, the wall closing behind them.

Gasping for breath, Dean fell to the ground, his adrenaline rush ebbing. He looked up to make sure everyone was okay. Merry was panting while she watched the Doctor ranting about something. Doesn't matter. Everyone was okay.

"Dean! Are you listening?" The Doctor kneeled down next to him, getting up in his face.

"Yeah, yeah, yeah." Dean drawled as he slowly stood up. "I'm getting everything."

"Are you?" The Doctor stood with him. "What was I saying, then?"

Dean thought for a moment. "Something about Grandfather?" He leered at the Doctor.

The Doctor returned the glare. "Actually, I was saying that-" He stopped. Then he started smiling. He giggled and started walking back into the pyramid.

"Wait, Doc, where are you going?" Dean shouted, confused.

He stopped and turned back around. "Take Merry back. Keep her safe. I won't be long." He fiddled with his bowtie before walking away again.

"What the hell are you doing?!" Dean asked again.

Without turning, the Doctor shouted back. "I've figured out how to stop Grandfather!"

Dean wanted to go after him, wanted to help him, but instead he turned around and walked toward the moped. Merry trailed after him, but didn't get on behind him.

"What are you doing?" She asked.

"Taking you back. Keeping you safe." Dean half smiled as he started the moped. "Come on."

Almost reluctantly, Merry climbed onto the moped. She wrapped her arms around his waist for safety.

"Is your arm going to be okay?" She asked wearily.

Dean smirked. He almost forgot about that. But he can still take her back. "Yeah. It'll be fine. I've had worse."

The moped roared to life as Dean took off. It was hard steering with only one arm. He almost fell off the moped a few times. But he and Merry had made it back to Akhaten soon enough.

Merry immediately got off the vehicle as soon as it landed, running up to her pedestal. She looked at the pyramid, searching for any sign of the Doctor. She looked back at the rumbling crowd of aliens with her eyebrows scrunched together. Like she was trying to figure something out.

"Merry, are you okay?" Dean walked up to her.

She didn't answer. Instead, she turned back to the asteroid and gulped. She looked nervous. She closed her eyes before taking a deep breath. She began to sing.

"Rest now, my warrior."

The sun shook, shaking the entire planet. Dean squinted, trying to see what was happening on the pyramid. The most he could see was a few beams streaming from the sun towards the pyramid.

Dean's eyes widened.

"Rest now, your hardship is over."

He ran back to the crowd, looking for a piece of cloth to secure his arm. He grabbed some from some weird lizard-thing, quickly tying it over his shoulder. Before running back to the moped, he took off his leather jacket and threw it over his broken arm.

"Live. Wake up."

Dean jumped onto the moped, starting it as soon as he was secured. The sun shook again, making the moped wobble as it took off. Behind him, the entire crowd joined Merry in singing.

"Let the cloak of life, cling to your bones."

There was a lot of intense turbulence on the way. The sun was going insane. It was swelling violently, sending out more and more beams of light. They seemed to be focused on one spot by the pyramid. Dean could only hope that it wasn't on the Doctor.

"Cling to your bones."

Dean was off the moped before it landed. He ran around the pyramid as fast as he could, but it seemed too late; the sun had imploded on itself, shrinking in on itself. The Doctor and fallen to the ground and was panting heavily.

"Wake up. Wake up."

"Doc!" Dean ran over, getting onto his knees to make sure the Doctor was okay.

The Doctor huffed and smiled, putting a hand on Dean's shoulder. "Don't worry. EVerything should be fine now.

The ground rumbled again. The sun was expanding again, almost smiling as it did. The Doctor let his head fall down in defeat.

"Live. Wake up."

Shakily, Dean stood up. He took his jacket into his good hand as he stepped toward the edge of the asteroid. He squared his shoulders as an act of defiance against the sun. It really looked as though it was smiling evilly.

"Wake up."

"You see this jacket?" He began as he held it out for the thing to see. "This jacket belonged to my father, John. He was a hero. He saved many, many people before he died. He gave me this jacket to prompt me to save as many people as he did. And he gave his life to save mine."

The sun screwed its face up, looking both annoyed and intrigued.

"And let the cloak of life cling to your bones."

"My father gave his life to one of the most evil things I've ever seen to save mine. His life ended early so mine could continue on." The jacket began disappearing from his hand, being taken by a beam of light. "He died so that I could live! So that I could protect my brother! And you know what, he died for nothing!"

"Cling to your bones."

"He could've saved so many more people if it weren't for me! He could've lived so much more of a life! There's so many more lives he could've saved, so many memories that could've been made if he hadn't died!"

"Wake up."

"If a thousand years of memory didn't satisfy your appetite, then take a million unmade memories from thousands of lives that were lost! Memories that could've happened, but never did!" Dean lowered his hand and glared up at the sun. "Their lives were ended too soon."

Behind him, Dean could hear the Doctor getting up. He wobbled towards him, putting a hand on Dean's shoulder.

"Wake up."

"He's right." The Doctor said to the sun. "There are so many already created memories, but an infinity of unfinished lives. Memories that could've happened, but never did. And an infinity is a lot bigger than so many."

The sun growled as it slowly began shrinking. Its face was struggling as it collapsed in on itself. It

grew darker as the sun totally disappeared.

Dean wiped the sweat off of his brow, subtly wiping the tears away as well. The Doctor smiled at him as he wrapped his arm around Dean's shoulder, pulling him in for a hug.

"Wake up."
