Sexy the brilliant mad human version of the craft she was currently in was humming to herself as she walked along the TARDIS. She knew every in and out, even rooms that have yet to be made, years from now that are tucked away within her mind. She wasn't looking for anything, just walking, stretching her legs out, humming as her fingers petted the wall as if she was comforting the ship or perhaps herself.
Four raps, she paused, listening again, then her pace picked up, she followed the noise, pausing at the door. She didn't have anything to fear, this ship is her or was her at some point in time. She open the door, pausing to peer in. Blinking at the man, her body straighten, she knew him...she did or she thought she did, sometimes things were a little confusing for her.
