At the end of A Love Betrayed, you’ll need to decide whether to kill Cynon there in the church, or wait for him to burn in the wicker man. You’ll have two dialogue choices which will have a significant impact on later events:
“Prepare to die.”
Eivor kills Cynon in the church. The wicker man will burn without anyone in it, but you’ll also be forced to kill Modron during The Gutted Lamb.
“You’ll die in the wicker man.”
Eivor tells Cynon that he can die in the wicker man. Cynon thanks Eivor. If you choose this option, you won’t have to kill Modron during The Gutted Lamb. You will still fight Modron, but you will have the option to spare her after the fight.
