So why we haven't seen any blood from rin's body? does it mean that she is not the real one?

When kakashi stab haku... you will see a drop/fountain of blood coming out...

While on Rin's body(not the blood in her mouth).... do you see any blood coming out? or maybe her blood was wipe-out by rain?

what's your thought about this?:shrug:
