"Doctor!" Sarah called out to him.

"What is it, Sarah?" The Doctor replied. He was currently in the TARDIS library, reading random books here and there. He was a teeny tiny bit angry that Sarah interrupted him, but when she calls out while he's reading, it's usually urgent.

"There's a llama in the TARDIS!" She shouted, looking to the llama and giving it a pat. The Doctor suddenly threw his book in the air and ran to the TARDIS control panel, trying not to trip over his scarf. When he got there, he was greeted with Sarah and a white llama.

"How did this get in here?"

"I have no idea! But it's so cute.. can we keep it?"

"It's slightly risky."

"Oh, please, Doctor?" she said, looking at the Doctor with puppy eyes. The Doctor tried not to say yes, but she was too cute.

"Oh, alright.. but take good care of it!" The Doctor told Sarah, as she suddenly started hopping up and down with joy.

"Oh thank you! Did you hear that? We're keeping you! Oh, I'll name you Harry..."

A week and a half later..

"Sarah? Oh, Sarah?" The Doctor called out. "Your llama is getting lonely.. oh, nevermind."

The Doctor turned around and looked at the llama.

"Well, aren't you a soft one.." He told himself, patting the llama awkwardly.

"Actually.."

And 2 minutes later, Sarah gets back in the control room.

"Doctor? I heard you calli- Oh my god."

"What?"

"... he looks magnificent!" Sarah said, walking to her pet llama.

"Oh, look.. you gave it your hat and scarf! Aw.. it looks so nice.." She said, hugging the llama.

"Well.. why don't we get another llama?" The Doctor asked Sarah as she looked at him with a wide smile.

"Oh yes."
