"You know how Sayori is really clumsy?"
"Well, she kind of messed up the whole hanging thing..."
"You're supposed to jump from high enough that the rope snaps your neck, making it quick and painless."
"But she just used a chair, meaning she kind of just left herself to slowly asphyxiate."
"But a few seconds in, she must have changed her mind or something..."
"Because she started clawing at the rope, trying to free herself."
"She must have kept at it all the way until she lost consciousness."
"That's why her fingertips were all bloody, anyway."
"Come to think of it, it was probably less 'changing her mind' and more just her survival instincts kicking in."
DIOS, BEBÉ SAYORI :(
