A.N. I am just cranking out this story so here is chapter 10! I am very excited about this chapter so i am releasing this one tonight as well! I am going to update this story more and more once i get this train rolling! Also this chapter has a more dark tone probably because I have a more dark tone to me so that made it easier to write! Anyway... Enjoy!

Marceline's P.O.V.

"Waiting for me Princess?" I state as I lean agents the wall in the darkness of the room. I watch her tense up as the initial fear runs through her. Soon after she relaxes and turns towards me. The moonlight illuminates only half of her face which gives her a sinister look. I smile a crooked smile as I cock my head. I watch her face shit to fear as I loom in the darkness of the room.

"You startled me, Marceline. What took you so long to get here? Everyone left a while ago." She states as she takes a step into the moonlight. The moonlight helps illuminate her beauty and I can barely contain myself. I give her a dark chuckle as I take a step into the moonlight. "Why are you acting like this?" She asks with a hint of fear in her voice.

"Acting like what?" I ask with a fierce tone.

"Acting so… so dark." She says with obvious fear. I use my super speed to quickly pin her agents the wall. I am holding her wrist with one of my hands as I turn her head to look me in the eyes with the other. I feel her begin to shake underneath my hold and tears threaten to spill out of her eyes.

"Because…" I say as I lean in and exhale deeply agents her neck. "I like messing with you." I say as I let her go and laugh.

"Marceline!" she yells at me as she rubs her wrist. I might have been too forceful with her by the way a darker pink mark is forming on one of her wrist. "You really scared me there…" She says as she looks down with obvious frustration in her voice. I continue to laugh as I wrap my arms around her waist.

"You know I was kidding!" I state with a smirk. I then feel a pain in my right shoulder as I feel her fist come down on my collar bone. I wince at the pain and quickly fly away from her and hiss. "Anyway, what was it that you needed to talk to me about?" I ask as I rub where she hit me. She sighs and sits down on her bed. I watch her closely as I lean agents the wall. She begins to fiddle with her hands awkwardly.

"How do you feel?" She asks as she looks down. "Physically." I look at her with a raised eyebrow.

"Why?" I ask slyly.

"Just answer the damn question." She says sternly. I look up at the ceiling and take a moment to think.

"I am in more pain than people know, but I pretend that I'm not." I say slowly. I watch her nod as she takes out the notepad and scribble something in it. "You're asking because you can tell can't you." I state with narrowed eyes.

"Yes, I am a scientist Marceline, my job requires observation." She says as she raises her eyes to meet mine. "From what I have observed it is your chest that hurts the most. I confirmed that when I hit you. So tell me Marceline, is it your ribs, your collar bone, or maybe your organs?" She says this all with eyes as dead as night. She is nearly impossible to read. I chuckle darkly.

"And I was the one being dark." I say with a deep chuckle. I watch her eyes narrow and a low growl forms in her throat.

"This is serious Marceline."

"I know." I sigh. "It's my ribs, they're still sore but I promise you it's nothing serious." I say as I begin to walk closer to her. "Now tell me Princess, what gave me away?" I ask with an obvious dark tone towards my words.

"Simple, the way you breathe when you sleep." She says with sass in her voice. I furrow my brows at her as I wait for her to continue. "Every time you breathed in deeply when you slept, your body would jerk." I flinch at her tone. "Honestly, it was quiet amusing." I grab her face and bring it up to mine.

"What is going on Princess? Why are you acting so dark?" I growl at her.

"Oh you don't remember, this is how I act when I am nervous." She states with a laugh.

"Nervous? Why are you nervous?" I ask with great confusion. She begins to laugh darkly as I cock my head in confusion. "Hey Princess, if you haven't noticed, I am in control right now. I mean I am holding your face." I say with fear in my voice. She just continues to laugh as suddenly she moves forward and our lips meet in a messy kiss. Our lips stay together for a second longer as she pulls away and after a moment of awkward silence she quietly says.

"I was nervous for that."
