I think things will start to build in suspense from here:
Diana: Why hello. You must be Vendella.
Vendella: Yes. Who are you, and why do you have these pups with you?
Diana: My name is Diana. The two conscious ones are my...slaves. They will obey me because I made them...loyal.
Vendella: Okay then. State your business.
Diana: I wish to ask a favor. I am aware that Cruella is seeking to take over the Dearlys' land.
Vendella: Yes. Why is it important to you?
Diana: I have a feeling that this boy band of attractive male pups will be instrumental in the defeat of the Dearlys.
Vendella: Indeed. But tell me...why do you betray the Dearlys?
Diana: I would have my reasons. I don't get the credit that I think I deserve with Roger and Anita.
Vendella: Very well. Scorch, open the door for our...'guest'.
Scorch: *grunts in agreement*
Diana: Okay Duke, Tripod. Throw the New Pups in that cage!
Duke/Tripod: Yes ma'am.
Diana: Tripod, have you dug up the files on this quintet of heroes?
Tripod: It's right here, ma'am.
Diana: Excellent.
Diana: Hmm...yes...okay...
Diana: Perfect. *They will meet terrible misfortune at my hand...*
Vendella: What's the story?
Diana: I am plotting to help you snatch the pups. Then Cruella may do as she wishes with them.
Vendella: Hold for ransom...of course...we can use the Ferocious Fun Pups to kidnap them all!
Duke: Uh, Diana?
Diana: What is it?!
Duke: I uh...think they're coming awake.
Noggin: Oh man...my head...
Lucky: Ohhh...is everyone okay?
Slayer: Yeah...but I feel like a banana whip.
Raiden: Hey, what's going on here? Tripod, what are you doing with these two?
Sanka: Yah, an' why's we inna cage?
Lucky: Not only that, but who's the Dal-babe?
Tripod: Shut up! Our mistress is going to speak!
Diana: My name is Diana. I am plotting to help Vendella and Scorch overthrow Roger and Anita's rule over the farm. Once the other pups notice you are gone, we will kidnap them all and make sure that Cruella does as she pleases with you.
Sanka: Oh mon...unlike McDonald's, I ain't lovin' dis.
Raiden: You fiend!
Noggin: Another villain? This farm's turning as malevolent as a KKK rally.
Slayer: I don't think I like this girl too much guys...
Lucky: Please...not another taping my fur...
Diana: You boys will get what you have coming soon enough. In the meantime, you two can guard them.
Vendella: We can always use some hostages.
Diana: In the meantime...Duke, Tripod...we are going to Hiccup Hole...
Diana: ...hee hee hee, victory is at hand!!!
Diana is one bad girl...
