Kai: Krys! /walk over Krystal/

Amber: that is not Krystal, Kai. Come back here.

Kai: What do you mean that is not Krystal? She's Krystal.

Amber: She's Krystal, but she's possessed. I know it, I can see ghost.

Kris: /shocked face/

Sunggyu: This is not the right time to play jokes Am.

Amber: I'm not playing jokes. Kris, you can communicate with ghost right?

Kris: Err /rub the back of his neck/ yes.

Sehun: Okay this is not the best time to play jokes.

Krisber: We're not joking!

Suzy: Why didn't you guys tell us earlier? 

Kris: Because it will turn out like this? You guys won't believe it.

Myungsoo: I believe it, because a few person is actually gifted with sixth sense.

Kris: I agree with you for the first time, Myungsoo.
