Welcome to the new series of mini-theories! Many undertale theories (including some of my own), have built off of other theories.. But, in this series, I'll be working from the ground up, with only the actual game and logic to start with. So, let's begin with the theory that both requires almost no speculation, and is used most commonly in the theories to come.

Now, there are two main foundations of theorizing that I use to narrow down possibilities. They're both pretty simple and intutitive. The first is that the theory cannot contradict any evidence in the game. After all, if it's proven wrong by something within the game.. It's wrong.

The second is what we know as Occam's Razor:If multiple possibilities still remain, even after exhausting all the evidence within the game.. The one with the fewest assumptions is usually the best one.

Now that we got that out of the way, I'll be explaining why Chara is certainly with Frisk within the events of Undertale. (It's also the first step to proving that they're the narrator, but we'll get to that in a later theory. All we're proving here is a relationship between Chara and Frisk.)

First off.. What is Chara? Well, they're the first fallen human, of course. When they fell, Asriel heard them, and took them home. According to the monsters in New Home, they became like siblings. (Whether or not they're right..? We'll discuss that in a later theory as well. However, this proves that they at least appeared to act like sliblings..) They came up with a plan to cross the barrier, kill six humans, and use that to free the monsters. What comes after in the plan is unknown. (At least for right now.) We do, however, know how things actually went through:When Asriel absorbed Chara's SOUL, the two shared control. Chara carried their own body to the golden flowers (this likely being the real meaning behind their wish), and were later spotted by humans, who thought Asriel killed Chara. Asriel refuses to fight, and instead takes blow after blow, as he returns to the castle, where he turns to dust. Chara and Asriel both die here.

So, we already know a few things. Chara knows Asriel, the player names Chara.. There's also a vital difference between Frisk and Chara:Chara's shirt has one stripe, while Frisk's has two. And Frisk doesn't meet Asriel (other than as Flowey) until the end of the True Pacifist Route. Now that we're all caught up, let's prove there that Chara is with Frisk, and, by extension, with the player. (The player controls Frisk:There HAS to be a relationship between the two.. If they aren't just one and the same, that is)

So, how do we prove that Chara is with Frisk, and, by extension, us? Wel, it's actually pretty simple. When Frisk goes to sleep in the Ruins, they have a dream.. One of Asgore telling them to stay determined That they're the future of humans and monsters.. To wake up. This can't be the narrator speaking to us, as the player, separate from Frisk, because, well.. We, the player, are awake. Chara's name is also used. Since it can't be Frisk, or the player, this is to Chara. It also matches Tape 5 in the True Lab. But.. Where did Frisk get that from, if they never met Chara before? If they never knew Chara well enough to get that dream...?

There is only one explanation for this. This is a memory of Chara. And for Frisk to get a memory of Chara.. Chara must be there, with Frisk. Therefore, Chara is, indeed, with Frisk, on all of the routes, at least as early as the end of the Ruins. (It can be proven to be earlier, but that's for another time.)
