Grandmother I need to talk to you
[concerned voice] What? What is it? Are you sick?
No, no. Grandma. I'm gay.
I'm gay Grandma. I have a girlfriend now.
[relieved voice] Oh honey, is that all? I thought you had cancer. Anytime someone needs to tell me something they are sick. Who's your girlfriend, when is her birthday? I'll bake her a pie.
TASHA: (to Clara) I have confidential matters to discuss with the Doctor. Would you excuse us?
DOCTOR: Anything you have to say to me, you can say in front of Clara. Well, quite a lot of it. Probably about half. Maybe a smidge under. Actually, Clara, would you mind waiting out here, please?
Yes. This is a thing called character development.
