F66r question

[Aga Tentakulus]

Quite simply.
The sentence was already finished with "den muss me".
It only means "den muss man". then you have to.
The correction "den muss de" then must this/this.
It only says that you have to do something, but it doesn't say what.
Question. Did he just not want to write what it is, or could he not finish writing it because of the space (sponge?).
But in order to write the sentence correctly, "de" simply became "des". That's the name of the whole sentence. "und den muss des" and then must this.  It just doesn't say what it is.
And you can see that the "s" was added later.
