Scaramouche is your enemy. He is the 6th of the Fatui Harbingers, and your only the 8th harbinger (you replaced Signora when she died). You thought that Scaramouche was busy, but you were wrong... He attacked you from behind and starts choking you

"Heh... I got you~!"

he says while still choking you, ruffling your hair with his other hand. You were running out of air FAST and you needed to do something quick
