[ Clara looks over towards the Doctor again. ] He's had a whole life before he's met me. Been so many places, done so many things. He's saved so many people. [ And saved her. ] That's not the same as what you and Tony have. You've had each other for so long...
[ Then, she stops.
Clara realizes that's really not what she's trying to say. She's just beating around the bush. A frown touches her face and she smiles sadly. ] I'm just a ghost really. He's told me he that we're not ghosts to him--people. But, that's what I am. I just stand in the background and help him. I try to keep him safe; to stop him from making horrible decisions. The kind that he'd hate himself over. I'm just me: Clara Oswald. Compared to everything else? I'm nothing. Which is fine! I don't mind being me. I am who I am.
[ The Impossible Girl who saves the Doctor. ]
It's just not the sort of thing to have anything with. It's not the same as what you've got with Tony.
[ Clara laughs embarrassingly. ] Sorry. You didn't need to hear all of that.
