"Doctor! Please, please. I don't know where I am."

Different faces of the Doctor swirled all around her, but he and Clara weren't the only people in the graveyard. Echoes of Clara's own voice surrounded her — at least, that was what she thought she was hearing. A smug voice — "actually, she was called Nina" — an amused one — "Blimey, you really know how to sulk, don't you?" and all around, "Run, you clever boy, and remember."

"These are my ghosts. My past. Every good day, every bad day," the Doctor — Clara's Doctor this time, said, emerging in front of her.

A gust of wind knocked Clara to the ground. Bits of debris floated around. "What's wrong? What's happening?" she cried out, panicked.

"I'm inside my own time stream. It's collapsing in on itself," the Doctor answered.

"Well, get out then!"

"Not until I've got you."

Clara looked around at the echoes of herself around the Doctor's time stream, in various outfits and states of dress, holding themselves in different ways — saying some things she would never say. "I don't even know who I am."

The Doctor's voice came, warm and comforting. "You're my Impossible Girl. I'm sending you something. Not from my past, from yours. Look up. Look."

The leaf Clara had parted with at Akhaten came floating down from the sky, landing on her hand. Some of the echoes of her leaned forward, interested.

"This is you, Clara. Everything you were or will be. Take it. You blew into this world on this leaf. Hold tight. It will take you home,"

Clara clutched the leaf, feeling herself fading out. If she didn't manage to escape, would she just become another one of the echoes she was seeing around herself now? Not real, but real enough to save the Doctor?

"You can do it. I know you can," Eleven's voice came, but it was farther away.

"How?" Clara pleaded.

"Because it's impossible. And you're my Impossible Girl. How many times have you saved me, Clara? Just this once, just for the hell of it, let me save you. You have to trust me, Clara. I'm real. Just one more step."

Clara took a step forward, and fell into the Doctor's arms.

"Clara, my Clara," the Doctor said, holding her head in his arms.

Clara felt her eyes closing unconsciously, felt herself drifting off into sleep. The Doctor picked Clara up in his arms, and walked out of the time stream.

Vastra, Jenny and River stood outside his time stream, watching with anxiety.

"You got her back?" Jenny squealed. She turned to Vastra with a big beam. "How?"

"I hope so," the Doctor answered, walking over to River. He set Clara down in between him and River, and she immediately leaned against River, still exhausted.

"God knows how that looks," Eleven said with a smile.

"When you say you hope so…" Vastra said, and then hesitated. "Which Clara did you get back?"

"Hopefully, the right one," the Doctor said, patting Clara on the shoulder.

"Theta. Theta Sigma," Clara said, looking towards the Doctor with a goofy smile on her face. "And I… and I know your real name now."

"Maybe not here, considering how that secret was the one that got us into this mess in the first place," River said with a laugh.

"Okay," Clara said, smiling.

"How does getting you back to the TARDIS sound?"

"Good," Clara said.

After a nap and some tea, Clara sat in the TARDIS's library, reading the Tales of Robin Hood.

Her head was still buzzing — like it did when she'd had too much to drink, or when she was thinking really hard about something. If she concentrated really hard, it was almost like she could hear voices. But she dismissed it.

She read in peace for a few minutes, until a crystal-clear voice came, childish and high. "Look at that picture! It's so pretty!"

The picture was a painting of Robin Hood and Lady Marian, and it was really pretty. "Who said that?" Clara said out loud.

"You don't need to be so loud. We can hear you just fine if you say it inside your head," came another voice.

"Because that's where we are!" the childish voice said.

Clara dropped the book on her lap, and tried to focus on what was going on. She could see herself in a comfortable alcove, looking out at what looked like a younger and older version of herself.

"Who are you?" she asked.

"We were born to save the Doctor," said the younger one simply.
