Yandere!Armin x Reader PART THREE!

You looked up in alarm as the door creaked open, you shrunk back, hoping it wasn't him...Armin. You closed your eyes, praying that it wasn't him...
"[f/n]? Is that you?" a soft voice asked. Your head shot up, tears filled your eyes as you saw a figure you hadn't seen in a long time...Mikasa.
"Mikasa!" relief was clear in your voice as you said her name.
"[f/n]! It is you! But wher-" she cut off short as she saw you crying.
"Mikasa...can you please untie me first? I promise I'll tell you what happened to-to Eren."
"Of course." she hurried forward to untie the ropes that were holding you hostage.  
You rubbed your raw wrists and hastily wiped away the remaining tears in your eyes and lifted your face to meet Mikasa's eyes.
"E-Eren...Eren's gone..." you couldn't even manage those few words without tears filling in your eyes, "It...was all... Armin's fault....".
Mikasa's eyes widened as she took in what you had said, "Well, the important thing now is that your safe." she put on a brave face and looked at you, "C'mon [F/n] we need to get you out of here before-"
"Before what?" a new voice joined in on your conversation. Your eyes widened and stiffened in both shock and fear...Armin.
"Mikasa, what a surprise to see you here." he spoke in calm voice not even backing down from the icy glare Mikasa was giving him.
"Armin, how could you do this, to me to Eren and most importantly to [f/n]?!?"
Armin appeared to not even be listening, he only looked up when Mikasa unsheathed her blades, preparing herself for a fight. He let out a tired sigh and pulled out once again the gun he used to kill Eren, this time pointing it at Mikasa instead.
"Drop your blades Mikasa, before I pull the trigger." his voice was deathly and ice cold, it sent shivers down your spine.
"M-Mikasa, listen to him..." you didn't know what else to do, you just stood there, helpless.  Mikasa dropped her blades and took off her 3D Manuver Gear and threw them to the side, close to you. The gears in your head made a sudden *click* as you thought of a plan, quickly and quietly, (while Mikasa was keeping Armin occupied) you snatched up the 3D Manuver Gear and blades and slipped them on, miraculously, Armin didn't seem to hear you. With a burst of speed you ran forward and plunged the blades deep into his stomach. Just as Armin's blood spurted onto your hands, Mikasa placed a hand on your shoulder, pulling you back. Armin slumped onto the ground, dead and you spun around to face Mikasa. Wordlessly, she extended a hand out to you and pulled you in for a hug.
"Don't worry [f/n], no one's here to hurt you now, you'll be safe.".

THE END?
