It crept like a predator does itâs prey. Slowly flowing through your veins and changing the way you think. At first you didnât notice, but The Doctor did. She notices everything, eventually.
Maybe you shouldâve said something earlier, when youâd been pricked by one of the plants in the alien forest you were walking through. You didnât think anything of it. Sometimes you forget that humans react differently to alien beings and objects.
It started with mannerisms, you had developed a twitch in your right hand, making a fist and unclenching it every 10 or so seconds.
You were last in line, behind Yaz. You were walking for a while, about an hour by now, The Doctor turning her head back every so often, making sure you were all there. That mustâve been when she noticed. You were each holding a torch of some sort, enough light around to be able to see the twitch you had acquired. She made a mental note for later.
While you were all walking, the others were discussing the other adventures theyâd been on before you joined. It made you jealous, even before this thing had invaded your body. It made you insanely jealous. Theyâd been laughing and recalling old memories for about 20 minutes before the jealous boiled over and turned into anger.
âOh my god will you lot just shut up!â It took you a moment to realize what you had just said. The group turned around, in shock.
âY/NâŚâ Yaz started as she took a step towards you. âare you okay?â You backed up, a hand at your mouth, in shock yourself.
The Doctor gently pushed Ryan out of the way so she could move towards you. âShow me.â
You pulled up your sleeve nervously. The prick you felt earlier had developed into a dark patch on your arm, a deep purple coursing through your veins. The Doctor took your arm gently, getting a closer look. Your heart was racing, her touch was usually what calmed you, but this time, fear was all you felt.
âI didnât mean to say that,â your own voice broke its silence.
âOf course you didnât,â She looked into your eyes. âThis isnât you.â
âDoc, what do you mean?â Graham piped up.
âThese plants are alive Graham, theyâre a living consciousness. Somethingâs really wrong here and I canât quite figure out what.â She sighed, and looked up at you. âBut I will.â
âLetâs keep going, Yaz keep close to her.â
Yaz let the others stay in front and linked her arm with yours, the side that wasnât infected.
As you walked, you felt your arm begin to burn, spreading out across your body, your grip on Yazâs arm tightened and her attention was back on you. You were there, present, but unable to control your own body.
âDoctor, itâs Y/N.â
The Doctor quickly moved to the two of you. You pulled away from Yaz and your clenched fist went to meet The Doctor face. She caught your hand.
âYouâll never understand. Iâm here, but you donât see me. You see the others,â you hear your own voice speaking your most secretive thoughts. Things you didnât know you were thinking. âYou never see me.â
She tentatively put a hand on the side of your face. You could feel her touch, it helped you, but only made whatever was taking control of you angry.
âGet off me,â your voice lowered. Violently brushing off her hand on your face.
âY/N, I know youâre in there.â The Doctor said softly, âI need you stay strong now. Weâll fix this, I promise.â The Doctor pulled out her sonic and directed it at you.
âIâm sorry,â The Doctor spoke quietly as she pressed the button. You feel your body gradually relax.
âWhat are you doing?â your voice angrily slurred. âWhat have y-â
Although it went dark, you could still hear as you were fighting for power of your own body.
âWhat did you do?â Yaz frowned.
âGive me a hand Ryan,â He helped pick you up and they continued to walk.
âIncreased her melatonin levels by accelerating her body clock. Essentially, I made her sleep.â
âHow long for?â Graham said.
âUsually Iâd say 8 hours, but with whateverâs inside her, 1 maybe 2.â The Doctor had spotted a building. âThere it is, not far now.â
The power of this being was overwhelming you. You were either getting weaker, or it was getting stronger. You didnât know, but you were losing hope, which only caused you to gradually allow the being to take over.
When the group arrived at the building, it was abandoned.
âLooks like a science lab,â The Doctor said, pushing left over materials off of one of the beds. âPut her down here,â she ushered Ryan over and had him lay her down.
The Doctor stared at your sleeping body and frowned. She was worried, hoping youâd have the strength to hold on.
âWhat do we do?â Yaz said. âWhat happens when she wakes up?â
âWell,â The Doctor started. âFirst we find out what happened here. These plants were never conscious.â
âOkay, but what about Y/N?â Yaz started. âSomethingâs taking over her body. Surly she canât hold on much longer.â
âSheâs strong, sheâll be okay.â
âHow do you know that?â Yaz snapped.
âYaz..sheâs doinâ her best.â Graham said softly.
âBecause sheâs Y/N and sheâs been through worse.â The Doctor spoke. A look from Yaz caused her to sigh and explain further. âIf we donât get whatever living consciousness is possessing her out of her within the next, oh I donât know, half an hour? Her mind, her consciousness, will die.â
âWe canât let that happen.â Tears began to form in Yazâs eyes. The Doctor walked towards her and held her shoulders.
âWe wonât,â She tried to comfort Yaz. âWeâll get our Y/N back. I swear.â A soft smile formed on The Doctorâs face. âNow, whateverâs happened, started here Iâm betting, so-â The Doctor started walking around the room, collecting files and papers. She went over to the filing cabinet and sonicâd it open, pulling out every document and dumping it onto a work surface âLetâs get reading.â
