(In the scroll library, Viper and Cassie are talking about the incident to Master Shifu)
Viper: It's the strangest thing, Master. I mean, why would a viper like me come into my room in the middle of the night?
Cassie: We thought maybe it came for the babies, but we didn't know why.
Master Shifu: (looking over each scroll) Hmm. What did it look like exactly?
Viper: It was too dark to tell, but I could make out black, green, and purple stripes.
Cassie: And it had really green eyes. The only other color you could see was his very small slit pupils.
Master Shifu: (sighing) Oh, dear. I was afraid of this. (Pulls out a scroll and opens it on a table) What you saw was the Green-Eyed Snake of Jealousy. It is one of the Seven Deadly Snakes of Sin. This particular snake appears when someone's jealous. It feeds on his or her emotions and will attack or maim the target of their jealousy. Tell me, is anyone you know jealous of someone?
Cassie: Not that I recall. Maybe someone's jealous of my relationship with Master Crane. Oops. I mean Crane.
Viper: If someone was jealous of your relationship with Crane, then the snake would've targeted you and not the babies. Come to think of it, the snake appeared after we took the babies in. Do you think someone's jealous of the babies?
Cassie: Hmm. Depends. Was anyone acting dejected and upset lately?
Both girls: Po!
Master Shifu: This may pose as a problem. We must diminish Po's jealousy if we are to defeat the snake.
Cassie: Are we going to tell him?
Master Shifu: No. Po might think it's his fault that he brought the snake into existence and remain upset.
Cassie: Ooh, that's bad.
Viper: I got it! What if we took Po out for a while? That should get his mind off the babies.
Cassie: I know! We can take him boat racing. He mentioned he wanted to do that.
Master Shifu: Some of you have to stay behind and watch the babies.
Cassie: Can I go with Po?
Master Shifu: Yes, and I must stay behind. Viper, will you mind staying here with me?
Viper: No problem, Master.
