Small Story Quest Theory
I have a theory on what these scenes elude to. The woman that states "I'm a hero, I should do what I want" while she's seen holding a vile of something. I think it could be a vile of possibly Balverine Blood. She could be turned into a Balverine with the vile.
Now the man that we see place cooked sausages on a trap, luring in the Balverine is helping our hero, but he seems wary as he does.
Sausage man seems to have had a way to save the woman, but when he didn't that's when the hero looks down the the sausage man outside the shop or tavern looking place with the line "we thought you could save her".
This leads our Hero on a quest to hunt down the woman turned Balverine and stop her.
We see later that sausage man is seemingly waiting for our Hero in a cave, to trap her, but it ultimately ends in the death of the woman turned Balverine.
TLDR: The woman next to the mc gets turned into a Balberine and the mc gets help from sausage man to save her, but turns out he can't which ends with the mc fighting the woman turned Balverine, possibly leading to her death.
