Marceline was gliding home when she saw it: Finn in handcuffs, walking toward the Kingdom between two armored banana guards.

"What the…"

It was unprecedented. The Hero of Ooo being made a prisoner? She had to have a closer look. She quickly made herself invisible and descended alongside the three, searching for clues. Nothing presented itself. They walked in utter silence. She looked to gauge their moods, but the guards' faces were obscured by the masks of their fireproof attire.

They must've taken him from Phoebe's place, she thought.

Her eyes darted to Finn. Given the circumstances, he appeared very calm. Even so, she could tell he was uncertain of what lie ahead.

Is Bonnibel losing it? Finn is, like, the most goodie-two-shoed dude in Ooo. I'd better follow along.

Back at the castle, Marceline glided in alongside Finn and listened as Bonnibel read the charges.

Oh, our boy Finn must be takin' it to the next level with FP. Adorable.

As the elite guards carried Finn off to the dungeon, Marceline decided to stick with Bonnibel and Jake. She wanted in on the juicy details.

"Who do you think you are?!" Jake screamed. This was the first time she'd seen Jake confront the Princess. Things were more serious than she thought. "You are out of your mind! Finn's just tryin' to figure out his deal—he doesn't need your jealous tantrums muckin' up the works all over again!"

"Do you not remember what happened when they kissed, Jake?! This isn't about me and Finn, this is about the safety of Ooo!" the Princess retorted. "This is treason, Jake! Conspiracy against the kingdom! I swear, if you try anything, I'll have your butt down there too. For aiding and abetting."

Woah, Bonnie. Calm down, girl. Finn's just tryin' to get his rocks off.

Jake crossed his arms and mumbled something to himself. Never had Marceline seen such a disgusted look on the dog's face. The elite guards marched back into the main hall and approached the pair.

"Guards," Bonnibel said. "Keep an eye on Jake."

Marceline watched Jake as the Princess made her way to the dungeon. The second she was out of sight, he melted to the floor and began weeping for his brother. Keeping their stealy composure, the two guards approached the quivering puddle and directed their spearheads toward him.

A'ight...Bonnie needs to take a step back. This is getting out of hand.

Marceline left the scene with haste and caught up with Bonnibel and Finn downstairs. She listened in on the brief interrogation, and bore witness to Finn's shame.

Jeez Louise—poor kid, Marceline thought. Bonnie really didn't know? You can sniff it out a mile away—of course Finn's a virgin! Making him admit it like that? What's she aiming at here?

Still concealed, she followed the two back upstairs to the main hall. As they entered, Jake stopped his sobbing, waiting to see if the Princess had brought his brother back. Marceline could see the hope in his eyes as they passed. It quickly faded as they approached the next stairwell. He shouted at the Princess, eliciting no response.

Oh, glob...the execution chamber is upstairs, isn't it?

The execution room was a redundant addition to the castle. Bonnibel had never been provoked to use it before. Even if she had, her good nature would've staved it off as a last resort. But for Jake, whose brother had just been charged with treason, the execution room must bear a heavy burden on the mind. Marceline could practically see the dog's heart break as Finn began climbing those stairs. Surely, he didn't believe Bonnibel would execute Finn. He'd have destroyed the castle by now if he did. Marcy tried to convince herself as they continued onward.

She doesn't seem like she's gonna hurt him. Why's she taking him up here, then?

It was a relief to see them enter Bonnibel's lab. Marcy slipped inside as the Princess shut the door. The interrogation continued...but Bonnie definitely had something else on her mind.

She's being way too comforting, Marceline thought. She's gonna drop a bomb here soon.

Bonnibel leaned in and licked the boy's face.

Okay...what the hell was that? Is she...trying to seduce him?

Marceline struggled to analyze the scene before her. It was plain as day, Bonnie had a thing for her little hero. Any time another princess came sniffing at her champion, she practically threatened them with war. Marceline assumed she was keeping Finn in tow till his eighteenth birthday. Then it'd be a free-for-all, as far as she could tell. Of course, she had let Phoebe get close. But according to Jake, that was a jealousy-fueled fiasco…

Marceline's train of thought was suddenly interrupted. Bonnibel had just dropped her nightgown. She was naked.

"Finn," she said sweetly. "Could you please turn back around?"

What. The. Fuck.
