Prologue:

"Here we are Clara back home." The Doctor said.

Clara frowned. "Home what for?"

"Well, this is where you live isn't it?" He replied.

She gave him a funny look. "But why am I home? Have I done something?"

He shook his head.

Clara came closer to him. "Then what's going on?"

"I have to go somewhere." He said avoiding her eyes.

"Where?" Clara asked folding her arms.

He just looked at her; his eyes looked grim and his silence worried her.

"I'm going with you." She said firmly.

The Doctor shook his head. "No, no it's too dangerous."

"I don't care I won't let you get hurt." Clara replied.

He smiled. "I'll be fine, I promise."

"I don't believe you." She said.

The Doctor placed his hands on her shoulders. "You have my word, I'll be fine."

Clara knew the Doctor long enough to know that he would figure out someway to trick her out the TARDIS so she relented.

Clara sighed. "Alright, fine but how long will you be gone?"

"Twenty minutes." He said.

She looked at him feeling so scared for his safety.

The Doctor crossed both hearts to reassure her.

Clara pressed her lips and nodded. "Okay." She said softly.

She stepped out of the TARDIS and looked back as the Doctor poked his head out.

"Twenty minutes." He promised before closing the door.

Clara watched the TARDIS disappear.

"Liar." She thought sadly.
