In a crowded room at a Comic Con, David Tennant is in the middle of a question-and-answer session with enthusiastic fans. Dressed in a casual but elegant suit, he juggles his natural charm with his humorous answers. Laughter erupts, applause follows, but suddenly, in the middle of the crowd, his gaze stops.

She is there.

Sitting in the third row, almost hidden behind a group of noisy cosplayers, is a young woman he knows too well. She is wearing a simple but elegant outfit, which contrasts with the rest of the crowd. Her eyes, which he has learned to read like an open book, stare at him with an intensity that disturbs him. His mistress. An actress fresh out of RADA, brilliant, ambitious, but also terribly aware of the insurmountable wall that separates them.

David continues to speak, but his words become mechanical, almost disconnected from his thoughts. His mind is elsewhere, torn. What is she doing here? She had promised to keep a low profile, never to mix their worlds.
