Game Theory: The KILLER’S Promise | FNAF Sister Location

Close Ad ×

It’s NEVER over with , and it’s NEVER over for ’s most notorious killer, William Afton, AKA the Purple Guy! With this latest installment of the franchise, I finally found something I’ve never been able to find in any of the games leading up to this one: a REASON for the killer to hunt down and kill children. Now for the first time ever we can put together pieces of the universe that have never made sense and finally understand who will “Put you back together…”



  1. Can you still do a slender man one?

  2. As soon as he said the one line:
    I think….Oh no, what dark things are we getting into….

  3. My favourite animatronic is bonnie but… What about bonnie? Why it appears
    only in fnaf 1 and 2?

  4. Now combine all your theories into one huge video so people can understand

  5. Okay, I had to do some thorough searching through your theory videos here,
    and what you’re saying is inconsistent here’s why:

    1. In FNAF Sister Location DECODED!, we established that the lines saying
    “I will put you back together” were spoken by “The Pigtail Girl”. So the
    promise isn’t coming from Afton (15:28)

    2. We established that phone guy is dead, and is Purple Guy. If Phone Guy
    is dead, Phone guy is Purple Guy, and William Afton is Purple guy, that
    must mean that Phone Guy is William Afton. If Phone guy is Afton, the Phone
    Guy must be alive. But he isn’t.

    3. According to you, since Phone Guy is William Afton, wouldn’t they speak
    the same? It doesn’t take long to see that the two people have very
    different voices.

    So I have a few questions about FNAF in general:

    1. If Phone Guy is William Afton, why do the two people have very different
    voices, and why is one alive, but other isn’t? (Don’t pass this off as a
    continuity error because Scott is not someone to do that)

    2. Who is the dialogue of Fredbear in FNAF 4 coming from? Is it the killer?
    If so, wouldn’t this disprove your theory that the promise of “I will put
    you back together” is coming from the killer since we established that the
    dialogue ISN’T coming from the same character due to the colour of the text?

    3. If William Afton is still alive, who is the one possessing Springtrap?
    We know that William Afton survived the Springlock failure and eventually
    go out of the suit, severely scarred, but the suit is possessed in FNAF 3,
    so wouldn’t this disprove your theory that William Afton survived a
    springlock failure and got out of the suit?

  6. No way he could survive springtrap

  7. yandere

  8. So, why is it the FNaF 1 animatronics that are focused as being possesed?

  9. But if fnaf 5 is before the four, 4 is before the puppet give life to
    animatroniks, how he knows about the giving life game ??????

    Here’s my timeline:

    FNAF Sister Location and FNAF4 takes place in 1983 at the same time.
    FNAF1 opened in 1987,a couple of weeks and its closed , months later FNAF2
    opened , one week and its closed.
    The owners of Freddy Fazbear’s Pizza wanted to revive the legend of the
    restaurant so they created FNAF3, and in it Purple Guy (or William Afton)

    did u know purple guy has been an animatronic all along… at the good
    ending Ennard scoops u and become your innards he is programed too kill so
    he made purple guy very guilty. anither fact u know he becomes your innards
    is because ennard is close too innards. purple guy went too there too be a
    nightguard because he wants too communicate with his children. the real
    villian is Henry because he made the animatronics kill hes the killer and
    the start of this. purple guy helped too make them so he knew that they
    kill and he wanted his daughter too not go close too baby. but she DIED.
    purple guy is the villian but Henry is the main villian so yeah just some
    tips ?☻

  14. If this like doesn’t get at least 15 by tomorrow my sister gets to slap me
    prove her wrong

  15. You should still do Slenderman

  16. Still doesn’t explain the rotten corpse in the Springtrap suit…

    My favorite episodes of GT are the Youtube Red ones.

    Said no one ever.

  18. my fav animatronic is mangle cuz he/she is misunderstood

  19. I agree the dialogue is the same as a little girl that you see in the mini
    game in for fnaf 4 what is the dialogue is the same for the family members
    of the boy like for example the girl that you see in the minigame has the
    same dialogue as the end of the game that says I will put you back together
    and like you said before purple guy is saying I will put you back together
    P.S. keep up the good work
