The Doctor spent the night trying to figure out what was wrong with Clara, but he couldn't. The Doctor crawled back up the tunnel so that he could speak with Ten.

"Oi!" Rose screeched pulling the blanket around her, "That was my leg you just squished!"

"Sorry," the Doctor mumbled as he crawled to Ten's window.

"What do you want now?" she asked frustrated.

"I need to speak with the Doctor."

"Who?" Clara called from downstairs.

The Doctor rolled his eyes, he had had enough of that word.

"Why do you need to speak with your past regeneration?"

"I need to ask if he's okay."

"Why wouldn't he be okay?" Rose was confused.

"You're here."

"Oi, what did I ever do to him?"

"I can't tell you that, but," the Doctor looked through the window and saw Ten attempting to peer back at them. "I need to speak with him. Alone."

"Fine," Rose grumbled. "Have your playtime, Time Boy, have fun talking too yourself."

She crawled through the tunnel, telling him that he should knock next time.

"Is she gone?" Ten moaned, pressing his face to his tinted glass, trying desperately to find out.

"Yes." the Doctor replied, "I believe that you might be creeping her out."

"How could I be doing that?" he asked, a defensive tone to his voice.

"I heard you sobbing 'Rose, Rose Tyler, I'm sorry. I wish I could have told you.'" the Doctor said, quirking an eyebrow.

"Well, I'm sorry for being upset."

"Over what?" a voice behind Ten demanded..

"I can't tell you that, Nine." Ten spat angrily.

"Yikes, what your knickers in a twist?"

"You."

"What did I do?"

"Try being the most cocky and annoying Doctor. Ever."

"Excuse me, how are you any different?"

"Well, this Doctor has the amazing hair."

"What does that make me?" the Doctor inquired, offended. He thought that he had the best hair.

"The Chin." Twelve piped up to the Doctor's right.

"I wish that people would stop making fun of my chin!" the Doctor shouted angrily.

"Then don't make fun of my ears." Nine voiced.

"Or my hair." Ten added.

"Or my eyebrows." Twelve contributed.

"Okay, fine. All of the Doctors from here on out shall not make fun of each other!"

"Ha, that won't last long." Twelve chuckled.

"What makes you think that?" Nine asked.

"I've done this thirteen times now."

"So I've done it ten times." Nine argued.

"Ah, you have but do you remember each time?" Twelve enunciated.

"Do you?" the Doctor questioned in surprise.

"If I did, so would you."

"I don't." Ten inputted.

"Exactly." Twelve stated.

"Then how do you know that this won't last long?" Nine asked, his face contorted in confusion.

"I just know myself."

"Of course you know yourself! You are yourself." the Doctor moaned, upset that Twelve had lied to him about being here and knowing the cure.

The gears turned in Ten's head as he counted the number of voices arguing. Twelve, Eleven, Nine.

"Oh no." he whimpered.

The Doctor turned towards Ten to find him shaking. With fear?

"What's wrong?" Twelve asked.

"I don't care." Nine announced angrily, finished with this conversation.

"I know who's next." Ten muttered.

As the answer clicked into their heads.

With that they remembered, everything that happened on the last day of the Time War. The 2.47 billion children that had lost their lives. When they were the man who
broke the promise.
