Vampire's Slips Into Night ability

[ZombieBobUSA]

I just need a slight rule clarification regarding the Vampire's Slips Into Night ability. It says "If no wounds are done to the Vampire during a Fight Round, he immediately escapes on the d6 roll of 5+, cancelling the Showdown."

My question is: If the Vampire were to escape in this manner, is this BEFORE the Hero would take any damage or after?

For example: During the Fight Round, the Hero would score no Hits on his Fight Dice and the Vampire would score 2 hits. Would the Vampire escape before the wounds are applied to the Hero or after?

I have been playing it where the Vampire would leave before doing damage to the Hero. But if Wounds are strictly Hits that have already been resolved, it would also sound like the Vampire would do damage and THEN escape.

Which is the proper way?
