So guys, here's an extra treat. Chapter 20. It's fairly long. but I hope you all enjoy.

Maria, who is possessed by the Demon, walks towards everyone. As she does, everyone backs away.

''Wow... I knew this girl was powerful, but I highly underestimated just how powerful she really is''. As Maria speaks, she holds her hands out, and the heat runs through her body, and fire shoots out of her hands. ''Woh, now that was fun''.

''We need to get out of here''. Aurora says, trying to back out.

''Oh, none of you are going anywhere''. With that the Demon, holds up both hands, and puts up a force field around the whole building, which means that nobody is getting in, or out.

''What now?'' Allison asks nervously.

''Now... We fight''. Aurora says calmly. She then goes to use her telekinesis, to send Maria flying, but Maria just deflects it.

''That seriously the best you've got?'' Maria smiles.

''Try me''. Astra, using her power, forms a cyclone in the air, having manipulated, the air, and sends it hurdling towards Maria.

Maria just holds out her hand, and as the cyclone approaches her, she quenches it, by closing her hand.

''Oh God... This is bad''. Cora states in fear.

''Ugh, enough already... You guys are so boring''. Maria just laughs. ''Now it's my turn''. Maria uses her Telekinetic wave, to send everyone in the room flying, and smashing into the walls. Then one by one, she decides to torture them. ''Now, who's first?''

Lydia is standing alone in the Old Hale House, thinking about the future fates of everyone. She knows how bad things will get if the Demon possesses Maria, but she doesn't know how to stop him.

''What are you thinking about?'' Peter asks standing behind her.

Lydia turns around. ''It doesn't concern you''. Lydia goes to walk passed Peter, when he grabs her arm. ''You're hurting me... Let go... Or i'll scream... And we both know that I can scream loud''.

Peter smiles and lets go of Lydia's arm. ''You being here right now, it has something to do with what you and Maria were working on, right?''

Lydia looks away.

''It's got to do with, you being a banshee... What did you do?''

''We got a glimpse of the future''.

''Really? And what did you see?''

Lydia looks at him, scared.

''What did you see, Lydia?''

''Gravestones... I saw gravestones''.

''Who's?'' Peter asks looking at her in shock.

''Everyones... Apart from Maria's... Everyone's gonna die... And there's nothing I can do to stop it''.

Maria has been terrorising everyone, and no one can barely stand.

''What are you going to do? Kill us all?'' Aria asks trying to get up.

Maria walks over to Aria, and crouches down beside her. ''She cares about you... She cares about most of you... So yeah, I'm going to kill, every, last, one of you... Because, nothing would give me more pleasure, than knowing how much pain, she'd be in... And the more pain, she's in, the strong, I am''.

Derek manages to get to his feet. ''That's never going to happen''. He wolf speeds towards Maria, and tackles her to the ground. Maria, uses her leg, to flip him off of her, and Derek lands on his feet. And from lying on her back, Maria, flips, to her feet. She slowly turns around and walks towards him, she looks him in the eyes. ''She likes you... Really likes you... So for that.. I'm gonna leave you til last... And, i'm even gonna let her watch, as I burn, your insides, and burn your ice, blue, eyes out''. Maria then, grabs Derek by the throat, and flings him across the room.

Scott then makes a run for the Demon, but Maria turns around and stops him. ''Ah ah, I wouldn't do that, If I were you''. Maria smiles. ''Scotty, the little cousin... You guys were so close growing up, and now look at you guys... There is a lot you still don't know about your cousin, isn't there? Well, too bad you'll never get to learn it''. Maria raises her hand, to use her powers on him, when her hand stops in mid air.

Scott looks at her in shock.

Maria's eyes then turn from black, to their original brown colour. ''Scott, it's time... You have to do it now''.

Scott just freezes.

Maria uses her other hand to bring a sword, flying off of the wall, into Scotts hand. ''Scott''. Maria raises her voice. ''I can't hold him much longer, please do it''.

Scott shakes his hand.. ''I can't... I'm sorry''.

Maria's heart sinks. And with that her eyes turn black again. And the Demon cracks her neck on both sides, taking back control. ''Hard luck... Maybe next time''. The Demon then sends Scott flying across the room, and the sword goes in a different direction. ''Now who's next''. Maria then notices Stiles. She walks towards him. Stiles backs away. ''Stiles... Gosh this girl's feelings... Must be exhausting... Caring so much... Well I can fix that''. Maria goes and pins Stiles against the wall. And both Cora and Derek, run and pull Maria off of him.

''Back off''. Cora says angrily.

''Awe... Young love... How sweet... Not... You'll regret that''. Maria sees a stack of wooden daggers hanging on the wall, and brings them flying across the room, and pins Cora to the wall with them, using her telekineis. Cora starts to bleed.

''Cora!'' Derek sees his little sister in pain, and goes for Maria.

''I don't think so'' Maria uses her telekinesis, and sends him flying once again.

Finally, Maria spots Aria once again. Her sisters are still knocked out after the telekinetic wave, having hit their heads and splitting them open. ''Aria, the last sister standing... Well, kind of... Do you have any idea, how long i've waited to do this?... After what you did... It's just a bonus that, i'm using Maria's body to do it''. She goes over to Aria, and grabs her by the throat, and lifts her off the ground, and pins her against the wall.

Aria is struggling to breath. ''You won't win''.

''But I already have''. Suddenly, heat starts to travel down Maria's arm, and into her hand, that's clenched around Aria's neck. It starts to burn Aria. Aria screams out loud, in pain.

Lydia and Peter are standing outside the building, where Derek's apartment is.

Peter looks at Lydia, worried. ''Did you hear that?''

Lydia nods her head, in terror. ''Uh huh''.

''We need to get inside''. But they can't. They try to open the main doors, and break windows, but nothing happens, as the force field is still up.

''What are we going to do?'' Lydia asks anxiously.

Peter just looks at her, worried.

''Have I mentioned how much of a pleasure it is, knowing that Maria's watching but can't stop any of it... It's a great feeling''.

Aria's eyes start to water in pain. ''Please, st-op''.

''No''.

Aria starts to slip unconscious, when suddenly Maria's eyes turn from Demonic black to her own brown eyes, in pain.

Maria lets go of Aria. As standing behind her is Scott, who has just suck the sword, through the middle of the spine. He then steps back. And Maria turns around, struggling to breath. Her eyes keep changing from black to brown, and back again.

Everyone looks at her in shock. And as her eyes are black again, she suddenly throws up black gue, and drops to her knees. Holding her stomach, where the sword has come through, and all the red blood is pouring out, Maria's eyes turn brown again. And finally she is Maria again. She looks directly at Scott. ''Thank you, Scotty''. With that she collapses onto the floor, her right hand still on her stomach.

Scott runs and skids to his knees beside her. ''What have I done?'' He tries frantically to get her to wake up. ''Come on Maria, please wake up... I'm so sorry''.

''Scott'' Derek puts his left hand on Scott's shoulder. Derek shakes his head. ''She's gone''.

Cora, who Derek managed to get down, is standing beside, a saddened Stiles. She holds his hand.

Aurora goes towards them. ''Give her space''.

Scott looks up at her, with an angry look in his eyes.

Aria goes over to Scott, and before he does something, he'll regret, she calms him down. ''It's okay''.

The force field has broken, and Lydia and Peter storm in. Lydia notices everyone standing around Maria, and goes over. She puts her hands up to cover her mouth in shock. ''Oh my gosh, It was wrong''.

Peter just looks at Lydia.

Suddenly a black cloud forms over everyone. They all look up at it. Then it goes to the far end of the room, and settles, and with that, this Demonic black figure, materialises infront, of them. And for the first time, it's whole.

The gang just look at it, terrified.

''Oh crap''. Stiles blurts out.
