MIRANDA: Doctor, is the squirrel going to live?
DOCTOR: There’s been massive trauma. We could of course try to save him but it would be costly, difficult and we’d have to send away for some special really tiny instruments.
GEORGE: Well, uh, are there any other options?
DOCTOR: We could put him to sleep.
GEORGE: What might that cost?
DOCTOR: Well, it’s by the pound. So … about 80 cents.
GEORGE: Well? <Miranda hits George> I was just - I’m curious, that’s all. We, uh. we’d like you to do everything possible.
DOCTOR: He, um. he’s not going to be the same, you know?
GEORGE: yeah. yeah. I know.
