A/N - 50th Anniversary special is next! Trust me when I say that you are not ready for it. So many reveals and even more questions! Might start writing it later.

The secret entrance led to catacombs.

"Where are we?" Clara asked.

"Catacombs," the Doctor said.

"I hate catacombs. So how come I met your dead wife?"

"Oh well, you know how it is when you lose someone close to you. It helps to have a backup."

One of the creatures appeared, following them.

"Clara, come on! Run, run!"

They burst through a steel door.

"Come on, quickly, we're in."

One of the creatures grabbed Clara.

"Doctor!"

"Clara!"

Elise and the Doctor pulled her away and the Doctor slammed the door on its hand.

Eventually, it pulled its hand out of the door and the Doctor closed it. "Yowza."

They headed up a set of metal stairs.

"Still a bit of a climb. I think I remember the way," the Doctor told them.

Clara started to falter.

"Clara? Clara. Hey, it's okay. You're fine. The dimensioning forces this deep in the TARDIS, they can make you a bit giddy."

Clara pulled away from him. "I know, I know. How do I know? How do I know that?"

"Clara, it's okay. You're fine."

"Have we, have we done this before? We have. We have done this before. Climbing through a wrecked TARDIS. You said things, things I'm not supposed to remember."

"We can't do this now. The TARDIS is a ruin. The telepathic circuits are awakening memories you shouldn't even have. Clara. Clara? Clara, what's wrong?"

"What do you mean, you keep meeting me? You said I died. How could I die?"

"That is not a conversation you should even remember."

"What do you mean I died?"

"The girl who died he tried to save. She'll die again inside his grave."

"Run. Run!"

They finally made it the entrance of the tomb.

Dr. Simeon was there with Madame Vastra, Strax, and Jenny. "The doors require a key. The key is a word. And the word is the Doctor's," Simeon said.

"Here I am, late to my own funeral. Glad you could make it."

"Open the door, Doctor. Speak, and open your tomb."

"No."

"Because you know what's in there?"

"I will not open those doors."

"The key is a word lost to time. A secret hidden in the deepest shadow and know to you alone. The answer to a question."

"I will not open my tomb."

"Doctor, what is your name?" Simeon grabbed the Doctor's face and the Doctor threw his hand off him. "The Doctor's friends and his precious daughter. Stop their hearts."

The creatures around them hissed.

"Madam, boys, combat formation. They are unarmed," Strax said.

"So are we!" Jenny yelled.

"Do not divulge our military secrets."

"Stop this. Leave them alone," the Doctor begged.

"Your name, Doctor. Answer me," Simeon said.

"Doctor?" Clara asked.

Strax picked up a stick and hit one of the creatures. It cut through its body. "Do you want me to do that again?"

They watched as the hole closed up.

"Doctor who?" Simeon asked.

One of the creatures reached into Strax's chest.

"Please, stop it," the Doctor begged again.

"Doctor who?"

"Unhand me, sir," Strax demanded.

"Leave him alone. Let him be."

"Don't worry, sir. I think I've got him rattled."

"Doctor who?" Simeon asked.

"Please!" the Doctor yelled.

One of the creatures was reaching toward Elise when the doors to the tomb opened.

"Why did you open the door, sir?" Strax asked, "I had them on the run."

"I didn't do it. I didn't say my name," the Doctor said, "Is everyone all right? Is everyone okay?" He rushed over to Elise. "Ellie? Are you okay?"

She hit him on the arm.

"Ow!"

"Never take that long again."

"I'm sorry." He turned to Simeon. "Now then, Doctor Simeon, or Mister G Intelligence, whatever I call you, do you know what's in there?"

"For me, peace at last. For you, pain everlasting. Won't you invite us in?"

The Doctor opened the doors further.

They walked into the console room, except there was nothing but pillars of the light. The cloister bell was ringing as they went up the steps.

Something was wrong here. Instead of one, there were 4 additional ones surrounding the one in the middle.

"What are they?" Clara asked.

"What were you expecting, a body? Bodies are boring. I've had loads of them. Nah, that's not what my tomb is for," the Doctor said.

"But what is the light?" Vastra asked.

"It's beautiful," Jenny commented.

"Should I destroy it?" Strax asked.

"Shut up, Strax," Vastra told him.

"Doctor, explain. What are they?" Clara asked.

"The tracks of my tears."

"Less poetry, Doctor. Just tell them," Simeon said.

"Time travel is damage. It's like a tear in the fabric of reality. That is the scar tissue of my journey through the universe. My path through time and space from Gallifrey to Trenzalore." He soniced it and voices came through.

"Have you ever thought what it's like to be wanderers in the fourth dimension?"

"Do I have the right?"

"Daleks, Cybermen, they're still in the nursery compared to us."

"There are corners of the universe that have bred the most dangerous things."

"You were fantastic. Absolutely fantastic."

"I'm the Doctor. I'm from Gallifrey in the constellation of Kasterborous..." That voice Elise recognized as the Doctor who saved her. The one whose brown eyes had comforted her.

"Hello, Stonehenge!" And there was the voice of her father. She had been the most proud of him in that moment.

"My own personal time tunnel. All the days..."

"It was the daisiest daisy I'd ever seen."

"Even the ones that I...uh...even the ones that I haven't lived yet."

"But I don't understand. Who do the other ones belong to?" Elise asked.

The Doctor walked up to up each of them. "This one is yours." The Doctor approached the three smaller ones. "These are your children's. Following in the family business."

"But why are we here?"

"Because the universe recognizes you as mine. We may not be blood, but you're my only family." The Doctor suddenly collapsed.

"Doctor!"

"Daddy!"

Clara and Elise rushed to his side.

"I shouldn't be here. The paradoxes. It's very bad," he said.

Simeon stepped closer to the Doctor's time stream.

"No. No. No. What are you doing? Somebody stop him!" the Doctor yelled.

"The Doctor's life is an open wound. And an open wound can be entered," Simeon said.

"No, it would destroy you."

"Not at all. It will kill me. It will destroy you. I can rewrite your every living moment. I can turn every one of you victories into defeats. Poison every friendship. Deliver pain to your every breath."

"It will burn you up. Once you go through, you can't come back. You will be scattered along my timeline like confetti."

"It matters not, Doctor. You thwarted me at every turn. Now you will give me peace, as I take my revenge on every second of your life. Goodbye. Goodbye, Doctor." Simeon backed up into the time stream.

There was a big flash and the Doctor thrashed around.

"What's wrong with him? What's happening?" Clara cried.

"He's being rewritten," Vastra told her, "Simeon is attacking his entire timeline. He's dying all at once. The Dalek Asylum. Androzani."

Elise started to feel weird as she watched the time streams of her future children flicker out. Memories were disappearing. "Daddy, I'm scared."

The Doctor managed to lift a hand to her face. "It'll be okay", he said, realizing what was happening.

Tears streamed down her face as the Doctor blinked. He was left holding only air.

Elise had disappeared before Clara's eyes.

"No", the Doctor breathed.

The one constant in his life was gone.

Forever.

In the blink of an eye, Elise was back. She looked around.

The Doctor was standing up now, but someone was missing.

"Where's Clara?"

"She jumped into the Doctor's time stream, restoring you and everyone else," Vastra explained.

"We are not all restored. I have to get her back," the Doctor said.

"But how?" Jenny asked.

"Is she still alive? It killed Doctor Simeon," Vastra said.

"Clara's got one advantage over the Great Intelligence," the Doctor told them.

"Which is?"

"Me. Now, if I don't come back, and I might not..." The Doctor turned to Elise. "Go to the TARDIS. Make sure everyone gets home. And then travel and be amazing." He kissed her forehead.

The Doctor suddenly spun around and grabbed at the air.

Elise watched as River appeared.

"How are you even doing that? I'm not really here," she said.

"You are always here to me. And I always listen, and I can always see you," he told her.

"Mum?" Elise asked.

"How can she see me?" River asked.

"I knocked down her mental barriers, allowing her to see you."

"But if you could see me, then why didn't you speak to me?"

"Because I thought it would hurt too much."

"I believe I could have coped."

"No, I thought it would hurt me. And I was right." The Doctor cupped River's face in his hands and kissed her. "Since nobody else in this room can see you besides me and Elise, God knows how that looked." He looked over at Jenny, Vastra, and Strax, who were looking at him oddly.

"There is a time to live and a time to sleep. You are an echo, River. Like Clara. Like all of us, in the end. She saved you, but you should've faded by now."

"It's hard to leave when you haven't said goodbye."

"Then tell me, because I don't know. How do I say it?"

"There's only one way I'd accept. If you ever loved me, say it like you're going to come back."

"Well, then." He stepped back from River. "See you around, Professor River Song."

"Till the next time, Doctor."

"Don't wait up."

"Oh, there's one more thing."

"Isn't there always?"

"I was mentally linked with Clara. If she's really dead, then how can I still be here?"

"Okay, how?"

"Spoilers. Goodbye, sweetie." River turned to Elise. "Goodbye, litter star."

The two Timelords watched her fade away.

The Doctor turned to Elise. "My brave, clever girl. Remember. Never cruel or cowardly. Laugh hard, run fast, and be kind." Elise nodded and he stepped back into his own time stream.

A few minutes later, the Doctor walked out of his time stream, carrying Clara in his arms. "Let's go home."

"Is she okay?" Elise asked him.

"She will be."
