no fogo de Pompeia, o médico encontra Lobus Caecilius
CAECILIUS: Who are you?
DOCTOR: I am Spartacus.
DONNA: And so am I.
CAECILIUS: Mister and Mrs Spartacus.
DOCTOR: Oh no, no, no. We're not, we're not married.
DONNA: We're not together.
CAECILIUS: Oh, then brother and sister? Yes, of course. You look very much alike.
depois de salvá-lo do vulcão no Natal de 2013, o tempo do médico que ele regenera para o rosto de Lobus, em seguida, na série 8, episódio 1 Deep Breath, ele começa a se perguntar por que ele escolhe esse rosto
DOCTOR:Er, have you seen this face before?
BARNEY: No.
DOCTOR: Are you sure?
BARNEY: Sir, I have never seen that face.
DOCTOR: It's funny, because I'm sure that I have. You know, I never know where the faces come from. They just pop up. Zap. Faces like this one. Come on, look at it, have a look, come on, look, look, look.
(The Doctor pulls Barney over to look in the mirror on the ground.)
DOCTOR: Look, it's covered in lines. But I didn't do the frowning. Who frowned me this face? Do you ever look in the mirror and think I've seen that face before?
BARNEY: Yes.
DOCTOR: Really? When?
BARNEY: Well, every time I look in the mirror.
DOCTOR: Oh, yes, yes, yes. Fair enough. Good point. My face is fresh on, though.
BARNEY: Er
(Barney moves away from the nutter in the nightshirt.)
DOCTOR: Why this one? Why did I choose this face? It's like I'm trying to tell myself something. Like I'm trying to make a point. But what is so important that I can't just tell myself what I'm thinking?
em seguida, na série 9, episódio 5, a garota que morreu, ele começa a perceber por que ele escolhe esse rosto
DOCTOR:I'm not supposed to. Oh. Oh!
(He looks at his reflection in the water and sees what he saw in the mirror back in Deep Breath.)
CLARA: What? What's wrong?
DOCTOR: My face.
DOCTOR [memory]: Who frowned me this face? Why this one? Why did I choose this face?
CLARA: Doctor, what's wrong with your face?
DOCTOR: I think I know why I chose it.
DOCTOR [memory]: It's like I'm trying to tell myself something.
DOCTOR: I think I know what I'm trying to say.
DONNA [memory]: (to Doctor 10) Just someone. Not the whole town. Just save someone.
DOCTOR 10 [memory]: Come with me.
(A memory of Lobus Caecilus cowering as Vesuvius erupts in Fires of Pompeii. Played by Peter Capaldi, if you'd forgotten.)
DOCTOR: I know where I got this face, and I know what it's for.
CLARA: Okay, what's it for?
DOCTOR: To remind me. To hold me to the mark. I'm the Doctor, and I save
people.
(He shouts at the sky - the Time Lords.)
DOCTOR: And if anyone happens to be listening, and you've got any kind of a problem with that, to hell with you!
