Jet indeed dodges the large corpse like Fist that punches out at her. The Grimm it's attached to emerges, Morana perched on it's back, "La Muerta Griselle. It's so hard to keep him down. He wants to play, So I had to give in. Go Griselle. Mangle some humans!" Morana jumps down, Landing without a sound next to Jet, "Isn't he just handsom?"
Chartre's Semblance doesn't seem to do anything. The blades are real enough and they seem to have retracted back into the ground.
Morana is interrupted by Jet letting off a series of punches that continue to arrive at their mark at a faster pace as two more arms are added to the equation. If Alanis were here she might note that the scene feels similar to some kind of Indian mythology based game. Or maybe some other Eastern Mythology.
