After playing two Pacifist Runs and zero Genocide Runs, I've come to the conclusion that I have to do my own Save-Goatbro story. And since I never intend to do Genocide, Chara is NOT going to be evil. Lemony and sardonic, yes, but not evil.

So here we are again. Everyone survived, the barrier is gone, and you are the hero of the hour. Again. Are you satisfied yet?
Still you, Frisk. What, you think if you stare into that mirror hard enough, I'll suddenly show up instead of your reflection? Come on. I might as well be your imaginary friend. This place has nothing else to offer you. You're too big for the bed, you don't like the toys, a dog ate the rest of the pie, and I doubt you want to eat any more water sausages.
Hey, what's that look for? Are you…? Come on, big kids don't cry. This is about him, isn't it? Frisk, you've done all you can. He's just like me. He can't come back. Just let it go. Come on, everybody's waiting… Where are you going? Back to the ruins?
You know what he's going to say. You've heard him say it more times than I care to count. Those words are seared into your memory, and yet you always sit through his whole speech. Nothing's going to change. He'll tell you he was wrong, thank you for listening to him, and give you a life lesson. Frisk. It's over.
You can't save him. Asriel is dead. Don't you have anything better to do?
...You see? I told you nothing would change. He's probably turning back into that flower as we speak. Or not. Nothing important seems to happen in this world unless you're there. Maybe if you refuse ambassadorship for the eleventh time, something will change… Why are you back at the mirror? …What do you mean, "we" haven't tried everything? I never had any part in your decisions. It was you who refused to fight. It was you who became so attached to this world. It was you who kept resetting the timeline, over and over, because you just couldn't leave well enough alone over a single person.
But… you are determined, aren't you? I suppose I'm more involved than I'm willing to admit; after all, you wouldn't have known half of what you do about monsters now if I wasn't there to check them for you. Does that make us partners? Fair enough, partner… what's the new plan?
…You can't be serious. You would seriously trust me with… that? After all I've done? Frisk, I hurt so many people. I did more to turn Asriel into Flowey than Dr. Alphys ever could. How do you know I won't ruin everything again? My hatred, my bitterness, my demons, what makes you think they won't get the better of me…?
Frisk, you really are something special.
Alright, partner.
We will save him together.
