[EP4 SPOILERS] Weird Chloe & Max moment?

The "Mercy Scene", at least that's what I call it. When you are given the option to assist Chloe in dying. After she finally exhales, I sat there for a minute taking it in and trying to hold other things in. All of a sudden Chloe's warm but slightly-sarcastic voice "Max, can you turn the page please? I can't cause I'm busy, obviously." Or something close to that, but she was already dead in-game. Needless to say it surprised the hell out of me. Also helped me cut the sorrow a bit because I couldn't help but laugh at the way she said it. Anyone else have this? Game bug or scripted?
