Possession (Gaster x Sans Fanfic)

How much I LOVE you

The night was more of a success than you expected. You admitted your feelings finally. Now, you are lying awake, thinking back on last night. You can remember all the new experiences. When you all walked home, you ended up staying at the skelebros' house. Your room was first and, before Sans went past, you gave him a peck on the cheek and winked as you shut your door. His room is right next door.

You sit up with your back to the wall that separates your rooms and turn, resting your hand and forehead against it. You just can't get over what happened. All your dreams came true from your first few timelines. In the more recent timelines, those dreams have been more ... lucid. They show your mental age, much older than you are due to the RESETs.

Ha. You really can't wait for tomorrow, right partner?

Chara?

You thought I wasn't coming back? Don't be so naive.

You believed they would come back but not now. You thought it was when you were at your lowest, they would appear.

You'd be surprised at how low you feel being separated from him. You aren't satisfied. Don't worry, I'm here.

What do they want?

You know what I want. Your SOUL. Give it to me.

No.

You don't have a choice.

If Chara is so powerful, why don't they just take it?

I can't. Not like this. But I have a friend. When a monster and a human SOUL unite, they become a being of unimaginable power, no matter how broken they both are. One fragment is all it takes. This power can do many things like bring someone out of non-existence.

Non-existence? Chara ran out of determination keeping them in this world. Ha. Serves them right.

My determination may not let me enter the world alone but it allows me to be determined to enter the world by doing whatever it takes. Turns out I'm not alone. There is one fragmented monster in non-existence who is more than willing to help me in return for your suffering and his little starlight. You shouldn't have made him so mad.

Tell him to back off.

He can't reach you without my help and I'd stop him before he hurts you. That's my job. He knows that and is more than satisfied to watch me hurt you. Oh and his shattered SOUL has left him unable to feel much except extreme emotions. He is obsessed like Flowey was but way more demented. I like it.

But they hate Flowey. He's a mockery of Asriel's memory.

Yeah because he was Asriel and it was wrong. My friend is much more interesting and it isn't someone I remember so it doesn't have the same wrongness factor.

You tell Chara to just leave. This conversation is pointless.

No it isn't. I only came to warn you to stop pushing my friend's buttons. I might not be able to stop him if you push him too far.

Whatever. Just go.

Fine. See you soon, partner.

So frustrating. They don't get it. There stupid threats aren't gonna stop you. That's how much you love him. Your willing to mess with a sociopathic, unstable non-existent god who is obsessed.

As for how much you LOVE Chara and this 'friend'. Well, you are ready to do whatever it takes to stop them and protect him.

No matter who it costs.

No matter who it costs. Such a pathetic dreamer.

They are only a child.

Not anymore. Those RESETs didn't stop their mind ageing.

So what? Makes them easier to manipulate and steer towards the End when they see the faults of the world.

They are determined and stubborn.

Yeah so if I set them on a road that leads to destruction in the right way, they will pursue it until it's too late and I can jump in.

You both are slowly nudging them down the path to self-destruction?

Correct. They are slightly unnerved and uneasy from my 'visits'. They don't want to lose what they have this time round; their perfect ending. This will drive them over the edge. If I nudge them certain ways, they'll go other ways until they can't save themselves. Even the one with the power to RESET becomes predictable over time.

And you get what you want?

Yes, I will keep my end of the deal. Non-existence will allow him to remain relatively unharmed by the destruction of his world.

Relatively?

Yes. He won't be hurt physically but the affects of losing everything you've ever known and cared for and then being forced into a realm of non-existence made of nothing with the destroyer of that world possessing your friend and a shattered monster as your only company will cause some mental problems for a bit before it becomes his new life.

Oh, that's what they meant.

Yes. Anyway, will you help me?

Of course. Anything for your starlight.

What about them?

They can't do anything. They can't save anyone. Only we can notice their presence. Non-existence is a gift sometimes.

They won't understand your riddles.

Indeed. You like talking directly to them. How cute. You must LOVE them.

No. They will gain LOVE from the readers.

Good to see you understand your position. We're going soon.

Of course. You're ready. Don't worry readers, we'll be quick. You won't feel a thing when your world experiences the End.

Like Flowey would say, 'That's a wonderful idea!'
