VICKI: You know, Doctor, I'm getting quite fond of Zombo.

DOCTOR: What?

VICKI: Zombo, it's his name. I gave it to him.

DOCTOR: Oh, yes, I see, I see.

VICKI: He's quite cute, isn't he, when he's like this.

DOCTOR: Well, I haven't noticed it before, my dear, but since you mention it, no I don't think so.
