Trying to only answer the questions you asked and not give away more
Lister is not dead
We still don’t explicitly know what they deal was with the sister but she is involved in the incident that lead sylhan to become like this
We don’t outright know what’s wrong with the medicine but it’s heavily implied that it caused negative symptoms and made memory loss worse
I am on chapter 20, the read is too painful and frustrating. Don't get me wrong, I love it, I wouldn't get past chapter 10 if I didn't. But please can someone tell me if Lister is dead or at least getting what he deserves (Death), and what was the original deal with is sister, what's wrong with the medicine (Please don't answer me just to tell me that I should just read and it's worth it, my brain is tired)
