The Doctor decided to have a little fun. She became oblivious. She nodded sadly. "It's fine, I get it." She said and threw him a half-hearted grin before turning around and walking into the TARDIS. And within seconds it started to dissappear. It was gone for a full minute before it came back. The wheezing sound announcing it's arrival. Then, the door cracked open and the Doctor peeked her her head out with a smirk. 

"Did I mention it travels in time?" She said to him with a teasing glint in her eye. She gave him a wink before she retreated back inside. The door still open.
