"Strange" and Burn Em Out Clarification

[Sylis]

So in the last game that we played, we tried Burn Em Out! for the first time and I have a couple questions.

1, Destroying the spawning pit.

"To destroy a Zombie Spawning Pit, a Hero must start in the space, give up their turn, and discard an Explosive. The Hero must survive any Zombie Fights in their space before the pit is destroyed."

So, the way we played, Hero turn starts on the pit, they discard the explosive and give up their turn, the spawning pit is then destroyed. Now, is that correct or does it have to go through a Zombie turn to have the pit destroyed.

Also, does the game end if the Zombie Player kills off two Heroes?

In the same game, I used the card that changes the Hero's keyword to Strange and does not allow Townfolk event cards to be used on them. Is that a normal rule with Strange characters like the drifter? Can Townsfolk cards not be used on them at all?
