But what is a kade?
I think the worst possible outcome is that someone does get infected during this - possibly Tuuri. Get a good stomach sinking moment as someone spots she has some rashes on her neck.
Since at such a conjecture they would find themselves deep within enemy lines with a very hard decision to make.
Of course, this could push forward a plotline where the crew risks all to go to Odense/fortress/military hospital in the hope of finding a cure.
And then, through Reynir's dreamquest to learn about A, we learn that there was never a cure. That ultimately, it might have delayed the symptoms, but it couldn't save anyone. She couldn't save anyone. Hence her current state of forgetfulness.
Though I don't think Onni would be angry at Lalli - he would be much angrier at the people who sent what's left of his family to die for a bit of money. You know. The people with whom he is actually, physically hanging out.
But idk. I hope this story is not going for maximum sadness. We can do that to ourselves, apparently.
