Coupe de Grace

Hi there, I have a question regarding "Coup de Grace": is the targeted Character dealt wounds as well or is he/ she just "defeated" and sent to topor, keeping the current bloodpoints?

The targeted character is just defeated. It doesn't take any damage, so you can't block or mitigate any damage with a Vagrant, etc. The victim's Blood goes to 0 when defeated, so they go to torpor with 0 Blood, but then add 1 Blood from their personal supply to the vampire as usual.
