A/N: Welcome to the second chapter of Unthinkable Agony. It will be switching back and forth between Princess Bubblegum x Marceline and Finn x Flame Princess. All the reviews for the first chapter made me so happy, so please keep reviewing. –Maiden of the Heavens (MOTH)

Pink with Envy

"How could he be so stupid!" Princess Bubblegum said angrily, nearly shouting as she sat down on her bed and covered her face in her hands. How could Finn be so careless as to fall in love with someone who was so unstable? So evil? And yet their relationship was not only lasting, it seemed to be thriving. If only she was thirteen again and express to Fin how she really felt about him. But she couldn't do that… that had been a one-time thing enjoying her childhood and pranking Lemongrass…holding Finn's hand. She thought for sure that with the pain that Finn and Flame Princess were causing each other that they would eventually break up and Finn would come running back to her. He would be her Hero of Ooo again. Then again when was Finn ever really her hero? He never truly had been her hero, but the hero for all of Ooo. He had rescued and saved people, protected her Kingdom. All the Kingdoms of Ooo. She might have wished to want to be thirteen again, but what would happen to her Candy Kingdom? She couldn't do that to her people, to her candy citizens. It would be far to selfish of her, besides Finn was nothing but a silly boy.

And there was someone else who already owned her heart. She felt a cold hand grip her pink one, and she looked up at the face that the hand belonged too. Marceline frowned and tried gripping her face on both sides to try to make her smile, before the Princess only glared at her.

"Bonnie what is wrong with you? Why are you glum and being a bummer?" Marceline questioned, but her coal black eyes drifted from the Princess sad face down to her t-shirt clad body and maybe just a little farther. Her eyes lingered longer than the Princess of the Candy Kingdom would have deemed appropriate.

Bubblegum's face puffed up with both annoyance and anger, as she released the hold that the Vampire Queen had on hand and looked down at her lap. "It's nothing…"

"Oh, please, Bonnie. It is not nothing. Let it out, Mrs. Proper Pants." Marceline said as she wrapped her arms around the Princess's shoulders and rested her head on his shoulder.

"It's Finn. He's dating Flame Princess…and he's just going to end up getting hurt…" Bubblegum finally admitted.

"Well, love comes at a price, Bonnie. And for those two pain is probably the price." Marceline said about to unwrap her hands from around the Princess of the Candy Kingdom, but Bubblegum stopped her and instead gripped her hands with her own.

"I-I think I might love him…" She whispered softly.

"Love him how?" Marceline asked and began to fiddle with a strand of Bubblegum's pink hair.

"I feel like I have to protect to him, and show him right from wrong. He's still so young…"

"So you love him like a little brother and you're his big sister?" The Vampire Queen asked, just to clarify.

Bubblegum nodded. "I'm worried about him, he's such a silly boy."

"Oh, don't worry Bonnie. It'll work out with him and Flame Princess you'll see." Marceline replied and strummed her guitar, her eyes then grazed Bubblegum's lithe body in the faded t-shirt.

The t-shirt she had given her.

"You really like that shirt don't you Bonnie?" Marceline questioned as she tugged on the fabric.

"I-I do. It's very important to me because you gave it to me." Bubblegum replied as a blush crept across her cheeks.

"Because I gave to you? Do you like me like you like Finn?" Marceline questioned as she floated in front of Bubblegum and continued to wrap one of pink strands around her finger, a blush coming to her own face.

Bubblegum looked at her dumbstruck for a moment. "No…I don't think so…"

"Then how do you feel about me?" The Vampire Queen pushed as she continued to strum her ax bass. "Do you like me like a sister?"

"I-I don't know….I-I don't think so…" Bubblegum replied and continued to sit on the bed while Marceline began to pick out certain notes on her bass.

And then to Bubblegum's shock, she began to sing: "You made a mistake one the day that you met me and lost your way. You saw all the signs, but you let it go. You closed your eyes. I should've told you to leave, cause I knew all the time you couldn't handle me. But you're hard to resist when you're knees begging me. I tear you down, I make you bleed internally. Can't help myself from you and it's hurting me. I don't have wings so flying with me won't be easy. Cause I'm not an angel, I'm not an angel. I hate being that wall that you hit when you feel like you gave it all. I keep taking the blame, when we both know that I'll never change…"

The words 'never change' echoed off of Princess Bubblegum's bedchamber walls. Red tears streamed down her cheek and began to turn pink. Bubblegum stood and gently wiped the tears away from the Vampire Queen's cheeks with her hand. Marceline's cold cheeks actually felt slightly warm with the blush that forming on her tears-stained cheeks. "So you don't like me as a sister?" she whispered hoarsely.

"I don't think so…not-not in that way…not anymore…" Bubblegum stammered also in a whisper and fell back on the bed.

"So what does this mean? What does this mean for us?" Marceline couldn't stop the questions from flooding past her lips.

"I don't know…" Bubblegum answered and lay back on her bed, closing her eyes.

Marceline was about to leave, the same way she had come in through Bubblegum's open window. But the Princess of the Candy Kingdom grabbed her hand and pulled her down beside her, and wrapped her arms around the Vampire Queen's waist, holding her close, their cheeks touching. Marceline didn't even bother to try to squirm her way out of the Princess's hold; she was actually, kind of enjoying it.

"So you don't like me as sister?" Marceline whispered as she coiled her fingers around Bubblegum's.

"No, I know that. And I don't like you as a friend either…" She whispered, feeling her face go as red as a cherry lollipop.

"Then how do you feel about me, Bonnie?" Marceline said as she licked one of her pink fingers.

Bubblegum tried to hold back a shudder that coursed through her body, but she couldn't and she could feel Marceline smiling against her cheek. "I-I like you very much…"

"But won't I ruin your perfect goddess persona?" Marceline hissed darkly.

"I'm not perfect Marceline. And I never said that you had to be for us to be together." Bubblegum sighed.

Marceline's face turned almost crimson. "I-I like you a lot too, Bonnie…" she had loved her ever since she had given Princess Bubblegum the t-shirt.

A/N: The song that Marceline sings is 'I'm not an angel' by the band Halestorm. Once again please review! I hope I kept them in character.
