My second fanfic, a quick little Eleven/Clara story that I hope captures the spirit of their relationship. Inspired by their final scene from "Journey to the Centre of the Tardis".
As the Doctor finished up a little cleaning of the Tardis console, Clara walked up the steps wrapped in a towel, her hair still wet. The Doctor turned and saw her and was flabbergasted for a moment.
"Are we back home yet?" Clara asked. "I have to get back to Angie and Artie."
"Clara, where have you been and why are you in a towel?"
"I just went for a swim in the pool," Clara replied casually.
"Clara, you can't just go for a swim without telling me!" the Doctor exclaimed in a near-panic.
Alarmed, Clara took a step backwards. "Why not?"
"In case you haven't noticed, there is no lifeguard on duty there," the Doctor explained. "We are the only two people in the universe with access to this ship."
"I know how to swim, Doctor..."
"But what if you suddenly pass out or start drowning for some reason?" the Doctor asked. "I have to be able to keep an eye on you while you're in there."
"Keep an eye on me? Oh, Doctor, you just want to see me in my swimsuit," Clara teased.
"No, Clara, that is not why..." the Doctor started to protest.
Clara took a couple of steps toward him and gave him a flirty smile. "All you have to do is ask..."
"No, shut up. I'm serious, Clara..." the Doctor said, exasperated.
"Are we really the only two people in the whole universe allowed in here?" Clara asked.
"Usually, yes."
"Well, that makes me feel like a very lucky girl," Clara said cheerfully.
With that, Clara smiled at the Doctor again, then turned and walked down the steps.
"Impossible girl," the Doctor said under his breath. "In more ways than one."
"I heard that!" Clara shouted from below.
The Doctor just smiled and shook his head.
