"We were lovers in a past life,
I can see it in your green eyes,
Maybe you were one of my wives,
In the long lost tribe.
There's just somethin' 'bout you I know,
Started centuries ago though,
You see your kiss is like a lost ghost,
Only I would know."
-Past Life, Kesha

Princess Bubblegum let out a sigh. What had possessed her to do what she was about to do? She looked up at the house before her, tucked away in a dark cave.

Marceline's house.

She walked to the front door and knocked hesitantly.

"Let yourself in, Finn, I'll be right there!" She heard Marceline call.

Bubblegum opened the door and made herself as comfortable as she could on the red couch before her.

"You guys are super earl-what?!" Marceline stopped, falling backwards a bit when she saw the pink princess sitting on her couch. "What are YOU doing here, Bonnibel?" She regretted the harsh tone of her voice.

Bubblegum winced a bit at Marceline's shortness, but no amount of sass from the vampire queen could stop her from her mission.

"I-I'm here because I've been doing a lot of thinking. And we've been getting so close again, we're finally sort of friends and I thought.." Bubblegum rambled.

"Thought what?" the princess felt Marceline's red eyes scan her body.

"Well," Bubblegum answered properly. "I thought I needed to give you a formal apology. For the past."

Marcy was shocked. She never thought Bubblegum would bring up the past again.

"Bonnie, what even happened in the past? I don't even know what I did. One minute we're happy together and the next you're pushing me away to build your kingdom...dating some cream puff guy.." Marcy spat.

"Marceline, you know I had to keep up a good face, I was trying to become a ruler of a kingdom! I wanted to be taken seriously!"

"And you couldn't do that with me?! Why were you always embarrassed of being with me?" Marceline hissed. Bonnie cowered a bit beneath her rude wording. This wasn't why she came over.

"Marcy, you wanted to explore Ooo, you wanted to travel, you had plans to go discover the world. I had plans to build a kingdom for all of the zombies that scattered the earth-turn them into living candy people. I wasn't going to get in the way of your life. And I was too afraid to let you into mine."

"I could have ruled here with you! I would have still traveled, it's not like you'd need me here 24/7. We were so happy, but obviously I wasn't fit for your perfect plans."

Bubblegum dropped her head. "You fit into my plans, I was just afraid. I'm sorry, Marcy. For the break up, for hurting you, for being the control freak that I was all those years ago. There is no scientific formula for love. I guess it's hard to wrap my brain around."

Marceline's resentment faded into understanding. Bubblegum always had trouble saying I love you. To hear her even bring up love put Marcy in a kinder mood. Bonnie had come all this way to make peace. Maybe it was time for Marceline to put her guard down, too.

"Bonnie, I could have made this one hell of a kingdom." Marceline smiled sweetly. She knew how hard it was for Bubblegum to relinquish control. "Apology accepted, your highness." The vampire bowed.

"No, you can't accept it like that!" Bubblegum exclaimed, hiding a smirk. "I didn't come here just for a truce..."

"Oh?" Marcy's eyebrow shot up. "Then what else did you want?" She teased.

"Marceline don't toy with me, you know I'm not good at this kind of thing." Bubblegum blushed.

"Hah. There's that pretty shade of pink that I love so much." The vampire playfully pinched the princess's rosy cheeks.

Her pinch soon became a hand folded around the side of Bubblegum's face. Marcy pulled the princess closer until their lips barely touched. Marceline then swung Bubblegum around into a passionate embrace.

"I love you, Bonnibel. I have for centuries. And I will for centuries more."

"I...um. I, erm..." Not this time, Bubblegum. "I love YOU, Marceline. I don't know where that puts us but I don't want to lose you again." She buried her head in Marceline's shirt. They then looked at each other and began drifting into a kiss.

"Are we, uh, interrupting something?"

Marcy and Bonnie froze. Standing at the door, with viola in hand, was Jake followed by a confused Finn.

"Uh, Peebles?" Finn gasped.

"Maaaaybe we should come back another time. Finn, didn't we say we'd visit Jake Junior today?" Jake hopped in front of Finn, flailing his limber arms as if they were noodles.

Finn looked at Marceline, then at PB, then at Jake then back at the two wrapped in each other's arms. A knowing smile crossed his once innocent face. He had grown up enough over the years to understand. Suddenly, everything made sense to him.

"We'll come jam another time. See you two around." Finn backed away with Jake in tow.

"I can't believe they almost saw us doing..!" Bubblegum screeched.

"Saw us what? Doing this?" Marcy grabbed Bonnie and pressed her lips to hers. Bubblegum's former stiff body relaxed as she drifted into the kiss.

They both heard a rustle in the bushes outside.

"Bonnie, I think Finn and Jake are spying on us."

The Princess composed herself before diving into Marceline once more.

"Let them."
