Carol facing the Red Scarves
The Red Scarves are an underground legion of thieves and assassins that include Spade among their members. Sash Lilac and Carol Tea were once members when they were making money on martial arts tournaments, but left after Spade started "crossing lines that Lilac and Carol wouldn't cross" which may include murder.
