Could you help me understand what "never" means in the following conversation (it's from a book)?
A man visits his girlfriend and he says: "Jesus,it's cold in here."
The girl answers: "Sorry. I've been in bed all afternoon. I've got a terrible cold."
"Never," he teased her. "Come on, let's sit you down."
Why does he say "never"?
Does he mean that he will never forgive her (as she said Sorry)?
Or is there another meaning for "never"?
Thanks for you help.
