Actually, Mansherry is planning to use her power after Leo stiches Law's arm back.

Maybe because Mansherry's power cannot revert a body back to its previous state (restore a cut arm), or maybe she can but it will drain her life forces (like how she can actually restore the SMILE factory).

Anyway, definitely excited for Gear Fourth!!!
