Definition of Defeating an Enemy and Villians Healing

[munkymuddface]

Looks like Villains heal up any time they are returned back to their cards, so, essentially, any time they are removed from the board (per zombie67's post above where he PM'd Mary Beth/Soundgirl). That's good enough confirmation for me.

As for the defeat/escape question, I just don't buy that defeating one and escaping from any additional is the correct interpretation of the rules. I still maintain that all henchmen that spot you must be defeated in order to successfully destroy the Hideout, until I see some errata or official clarification that says otherwise.
