A/N: Have not finished all seasons so if this I mess up canon, apologies.

"Where is he?" Bubblegum demanded, pink hands balled into fists at her side. The night was brightened by the full moon, warm but not sweltering. Bonnie had found Marceline wandering near Finn and Jake's place.

"Uh, who?" Marceline replied, raising an eyebrow. She lowered herself to the ground from her floating position.

"You know who!" She snapped. Marceline shrugged her shoulders and shook her head.

"I really don't, Bonnie."

Bubblegum made a frustrated noise and muttered something in German. "Peppermint Butler is missing. He's red. What did you do, Marceline?"

A snarl left Marcy. "So you just assume it's me?" She snapped, eyes narrowing.

"Uh, yeah." Bonnibel said, crossing her arms. She was standing stiffly, but confidently. As always. "You literally consume red."

Marceline scoffed in disbelief. "So you think I would take Peppermint Butler and just eat the red. Me, of all people, the one you would kill if I took him? Seriously, Bonnibel?" She sneered at the Princess, offended at the accusations. Never. Good. Enough. Marceline thought. Their past, their shared kiss- but she was just her problem. A nuisance. A Vampire Queen and the Bubblegum Princess would never work, anyhow.

Bubblegum paused, studying Marceline for a few long, silent moments. She sighed heavily and her arms dropped to her side.

"I can help you find him." Marceline said. "I didn't take him. Why would I? You would automatically assume me, obviously." She huffed.

"That... would be nice, Marcy."

"Where else do you think he would be?"

The Candy Kingdom Princess and the Vampire Queen wandered around Ooo for the entire night. Bonnibel got more distraught as the night went on, although she tried not to show it. Marceline could tell. She said nothing.

Bubblegum was so pretty with the silvery moonlight shining on her pink skin. Her hair was short now, whereas Marceline's was long and thick again. Bonnie wore simple clothes- a hoodie and pants. Marceline was similar in her usual tank top and jeans.

"What are you looking at?" Bubblegum asked. Marceline's eyes grew wide and she cursed internally. She had been looking at the Princess and gotten caught. This again? Marceline thought, groaning internally. She shrugged at Bonnibel.

"So uh, how long has he been gone?" Marceline asked, changing the subject.

"Days!" Bubblegum exclaimed. "I know he sometimes leaves for a day or two, but an entire week? This is highly abnormal for him."

Marceline paused, thinking. It was then that the strong smell of peppermint hit her. "Hmmm..." Marceline smelled the cooling night air. Dew, animals... peppermint. "This way." She said, pulling Bonnibel along with her.

They reached the mountain cave as the horizon began to slowly light up. "Here. He's in here." Marceline said, pointing.

"Uh, are you sure about that?" Bubblegum was skeptical. Marceline rolled her eyes and lifted Bonnie up, lifting her up to the cave with ease.

"Holy..." Bubblegum gasped, jaw dropping.
