No, I usually tell the guys that they are, like, poisoned. Otherwise, it's a bit of a paradoxical situation: the player is dying, but doesn't know it. Although, this doesn't mean that he should shout loudly so that they can heal him.
The redhead was healed by the chaplain.
Maybe the samurai was executed?

By the way, if the redhead was only healed, then among the displayed NDs, we are missing the isolation of the creature. And I don't see any other explanation for this other than the fact that the creature was Alex. I'm waiting for the redhead's opinion.
