Chapter 4

The world seemed to stand still around the blonde adventurers as they silently stood, watching the other with empty eyes as the air grew thick with tension. For a long time, neither of them spoke, to shocked and scared that if they did then reality would just shatter all over again. Finally, after a long while, Finn took in a deep breath and bowed his head, finally finding the words- Or rather word that he needed to say.

"Wha... WHAT?" Finn stuttered, reaching up to take off his bear hat and run his fingers through his short blonde hair, his fingers trembling through the knotted mess.

After that, he let his hand drop back to his side with a dead thud, then folded it behind his back as he started pacing. He had no longer had any more words. At least, no more words to actually say out loud to Fionna anymore. His mind, however, was racing with his own personal questions that he asked himself.

'How could I have a twin and not know it?' He thought, halting now in his pacing to fully take things in once more. 'How could I forget that!?'

"Finn, you... I mean we, have nothing to worry about... Martin was thrown in jail as soon as he landed in Ooo..." Fionna said, putting a hand on Finn's shoulder."He is serving a life sentence without bail... So its not like he can get out or anything, not unless-"

"Oh Glob... Fionna, please don't get mad at me." He cut her off suddenly as Fionna bit her lip quickly and looked very confused.

"Why would I get mad at you?" She asked as Finn took in a deep breath and held it before speaking.

"I sorta... Freed him from jail..." He confessed hesitantly, tensing up a bit as his sister's face dropped into an expressionless one. "I didn't know! Billy just told me dad was alive so I- Yeah..."

Fionna didn't say anything for a long time after that, simply staring at her twin with that same emotionless gaze for longer than he felt comfortable. Finn was already getting very worried, still staying tensed up as he waited for her to react. Then out of now where, she screamed, seemingly as loud as her little lungs could handle. Gasping loudly over her screams, Finn ran to her side and began to shake his screaming sister.

"Fionna, I'm sorry. I was stupid, and I didn't know. I have been looking for him since I was 13... Please calm down." His voice cracked at the painful memory of meeting his father.

At that moment, Marshall the vampire king, Marceline the vampire queen, Jake the dog, and Cake the cat came running out of the house to see what all of the noise was about. Upon seeing Fionna, Marshall flew over to her and clasped both hands onto her shoulder to silently ask her what was wrong. She tried to speak, but hardly could with her now crying. Marshall just picked her up and started to calm her down as he headed inside with the thrashing blonde in tow. The others were left in pure silence, as they all suddenly looked at Finn like he had personally wronged them. Well with Cake, he might have. Slowly and painfully, he lifted his head, intent to explain what had happened, knowing Jake would instantly understand the situation. Cake, however, would not understand and instead she simply sighed before opening her ears to him.

"Fionna just told me that... We're twins..." He began, biting his lip gently as he looked away.

"No way!" Jake gasped, his eyes widening as Cake rolled her eyes in a 'no duh' way. "How did you not know this!?"

"I didn't! And then we started talking about dad an-" This time it was Marceline's turn to cut in.

"Martin? That crazy old dude you let out of prison?" She scoffed, adding insult to injury unknowingly.

"Yes, and that's why Fionna got all crazy like that... Apparently he wasn't supposed to be let out and I did but it was an accident cause I didn't know and everything else just turned out all stupid and whatever..." Finn got out in one breath, stopping only when his face was beat red.

Cake, who had heard just about enough, threw her arms up into the air and quickly gained the attention of everyone around. Truth be told, fury just wasn't enough to describe the look in her eyes which closely mirrored that of her sister's. She didn't yell though, knowing that Fionna would need her to be sane at this point, and slowly began to lower her arms as she took a few deep and calming breaths. With a final deep breath, she turned sharply on her heels and began to head back towards the house, the sounds of Fionna's screams of rage filling the now empty air between the two.

"We will deal with this tomorrow," She said suddenly, pointing a finger over her shoulder and in Finn's direction as she left.

'Tomorrow.'
