Once you’ve subdued King Rhodri during King Killer, you’ll need to decide what to do with him. You’ll have three dialogue choices, but it doesn’t matter which you choose. Ivarr has a plan that he’s determined to follow.
“Let him go.”
Eivor asks Ivarr to let the king go, to be humiliated. Ivarr insists that he has something else planned for him.
“He is dying.”
Eivor insists that Rhodri is dying, and to let the Nornir spin his fate from here. Ivarr disagrees and pursues his plan.
“Finish him quickly.”
Eivor asks Ivarr to kill Rhodri now and be done with it. Ivarr refuses and follows his plan.
