...what?

Chara was definitely gone by the time the cyan human came around.

And the cyan SOUL definitely went into a jar.

And the royal family definitely didn't watch their child murder a human in cold blood.

What THA meant there was that the cyan-SOUL human has a very small, but nonzero, chance of having fallen between Chara's death and Toriel moving to the Ruins.
