Warning: MAJOR Undertale spoilers!! If you have yet to achieve the True Pacifist Ending, please do not read (although tbh you’ve probably been completely spoiled by being on this website alone, but yeah just in case) .

So during the fight with Asriel’s last form, the fan-proclaimed “God of Hyperdeath,” you/Frisk gain the ability to SAVE the Lost Souls of your friends. Toriel, Asgore, Sans, Papyrus, Undyne, and Alphys can all be reached through the power of your DETERMINATION.

However…

After you SAVE them all, Frisk then realizes there’s “someone else.” There’s one last person, one last SOUL lost in the darkness, but resonating just loud enough to be heard.

The player’s first assumption is of course that it’s Asriel, which is not a very far-fetched idea since obviously he must be reached out to as well.



But…

You don’t call his name; you call their name.

You’re trying to SAVE Chara.

Chara, the “demon that comes when people call its name,” is calling for your help. To be SAVED. And when you do, you trigger these memories: Chara’s memories.

Then, and only then, can you save Asriel. It is only by SAVING Chara can you then SAVE the final, remaining SOUL.

By SAVING the Lost Souls, the player/Frisk seems to restore them to their normal state and thus their bodies. Perhaps by SAVING Chara, you then lay them to rest? Or maybe…

Maybe they help out? Maybe, as a sign that you the player through Frisk has shown them that not all human beings are evil, Chara has a full change of heart, and thus it is through a combination of their DETERMINATION and Frisk’s that resists Asriel’s final attack in order to SAVE their best friend…?

But of course, that part is just speculation. The only real fact here is that you truly can reach out to the broken, lingering SOUL that is the first human, Chara. And the even more amazing thing is, you succeed.
