You smirked at Fionna. She was asking who you were, but that could mean anything. You looked at her and asked rather pointedly.
"What exactly are you waiting to hear in response?"
She stared back. "At first, I wanted to know what got into you."
"Of course." You shrugged. That was easy enough. Asuka as well relaxed when she clarified but the two of you grew a bit more tense when Fionna began to speak again, adding.
"But, this goes way beyond that. It's like you're a different person. So... I still wanna get to the same point, but I'm gonna need you to explain to me pretty well why you're like this. Because you are literally just a different person, basically. What's going on, are you crazy? Like, seriously crazy?" She asked in a worried tone, which was the only thing that stopped you from responding sarcastically. You scratched your head and thought of a good enough answer that could satisfy her.
"I am a different person. Finn was possessed and now I'm taking over until he can come back." You admitted.
`Djir that is WAY too much information! She's not going to be able to handle that.` Fin complained.
`If she can't handle it she shouldn't have asked.`
Fionna stared at you long and hard. After a few moments she stood up and hugged you tightly and rubbed your back. Since she was a bit taller your face was being pulled into her shoulder.
"H-hey! What're you hugging me for? I just said I'm NOT your brother."
She nodded slowly. "Right. I should've paid better attention. Mom's usually busy and Jacob isn't a dad, no matter how cool he acts."
Asuka and Su squinted at one another. Su mouthed 'cool' at her with a visual question mark of her head being cocked to one side. Asuka shrugged in response and made a cutting motion across her neck, suggesting that the moment should not be interrupted by them. Su nodded in agreement, content to lean forward and watch like someone who needed a bowl of popcorn.
Fionna continued. "I guess that break was worse than any of us thought. I'm sorry for brushing you off, Finn. I was too concerned with my own diagnosis that it biassed me against you. I thought that because I was fine and getting better that you were, too. But you're obviously not fine." She released you from the hug and leaned back.
"Do you actually feel like someone else or is it just you being edgy?"
"I actually feel that way." You uttered indignantly.
"I actually feel like a different person. How many times you gotta ask the same thing expecting a different answer?"
She nodded slowly. "Seems accurate. Normally you couldn't talk to me this way. Normal Finn definitely couldn't talk to girls, either. Let alone bring them home or be naked around them without getting flustered." She turned around.
"What about you two? Was there a change?" You looked at them and shook your head as she turned her back.
"Well-" Asuka was a terrible liar. She was flushed as she tried to express the falsity that you had not changed at all. Su noticed Fionna picking up on it immediately and sighed deeply. She raised her hand.
"Not going to be able to hide it. You're not good enough at that." She said in your direction before regarding Fionna seriously. She looked up and cleared her throat.
"I've had testimony collected about his behaviour before and after. It's not just a shift, it is a marked difference and it seems to be consistent. In asking the school nurse she said-"
"H-hey why'd she tell you!? She's got that oath thing!" You complained loudly before Fionna shushed you.
Su corrected herself. "A... non-specific source said that the change was consistent with an alternate personality. That is what I've been able to gather through my own channels."
Fionna was listening to Su closely, nodding along. "You're the girlfriend?"
"That's right." Su smiled, winking at Asuka in particular. The red-head looked assaulted.
"What colour underwear does my brother wear?" Fionna asked suddenly.
"What the hell kind of question is-" You and Asuka said at the same time, trading a look at the strangeness of the scenario. You and her were the only ones that were really in on the truth.
"There is a gradient package of trunks that your mother purchases on repeat each 6 months. Black to Dark Blue. Now... He does own a few pairs of womens black lingerie but those were purchased by someone else other than him or your mother."
"H-hold on-" You stammered.
"That's all correct. Impressive. But what is his favourite band?" Fionna looked down her nose at Su intensely. In response, Su chuckled and shook her head lightly.
"Trick question. Finn will refuse to state an exact preference. He likes 'all music' and has not shown any new preference. He will also not admit to being a fan of any of the bands he has up on his wall as posters."
Fionna whistled to show she was impressed. "Not bad. Grades are something I don't even have to ask."
"Pfft. Straight A, until recently... Give me a harder one."
"Thought so." Fionna crossed her arms over her chest and tapped her foot as she took a few seconds to think.
"I know: Who is Finn's favourite woman? Not counting our mom."
"Me." Su claimed.
At the exact same time Fionna answered. "Obviously me... But you answered correct on all the other questions which leads me to believe that you are obsessed with my Brother. Hm."
Su closed her eyes and shrugged before opening them to stare up at Fionna competitively.
"The fact that you know that I am correct on ALL of the questions means that you are obsessed with him in equal parts, no?"
"More obsessed than-" Fionna tried to say before Su interjected while standing up and facing off with Fionna.
"I don't think so. I never undertake any effort half-heartedly which means that I am currently Finn's biggest fan." Su claimed.
Su lifted her brows as she cocked her head to one side and asked in a bitchy tone.
"Currently? When are you planning to drop him like he does to his 6 month old underw-"
