"When was the last time you remember doing something during the day?"
"What do you mean?"
"I just mean during the day. Daylight - when was the last time you remember seeing it? I'm not talking about some distant, half-forgotten childhood memory, I mean like yesterday. Last week. Can you come up with a single memory? You can't, can you? You know, I don't think the sun even... exists... in this place. 'Cause I've been up for hours and hours and the night never ends here."
