Hierophant, Marceline and others in “May I Come In”

Marceline, listen to me. You will never defeat the Vampire King. You can't even defeat me in your current state. [Marceline sits down in Jake-House]

Marceline

All right, what do you want?

The truth is, I hate the King as much as you do. He's a total dink. I came looking for you because I want to team up. Then you started tempting me with boy blood [LSP flirts at him saying "Hey!"] and hurling spiky purple gobs at me. Here's the dope. You need me. [Marceline moves LSP back]

Yeah, okay, girl, you got this.

I don't know how it finally happened, but... he must have let you beat him.

Am I right?

Marceline

[beat, facepalms] Ugh!! All right. Say we do work together, you need to give up drinking blood. [turns invisible]

I'm a vampire! Drinking blood is kind of the main thing.

Marceline

And you can drink red just as easy. [he grunts] No hurting poor, scared blood-filled animals.

[beat] Well, then I suppose I have no choice. I'm just going to waste you [grabs Marceline by the neck] and eat that kid because that's what an old-school vampire does! [behind the rustling bush comes out a crying Crunchy]

I don't wanna play anymore! [bumps Hierophant into Jake-House]

[gasps] No! I-I wasn't invited! [disintegrates] NOOOOO...!!

Finn

Geez. What happened?

Marceline

Dude was too old-fashioned for his own good. He just couldn't get with the times.
