bengeddes: Sounds like you've got all the details.

My first time I wasn't as clear about Abigail's involvement. She seemed less innocent in later replays.

One thing I always thought was strange is that Mikul seems very upset that Ilsa died. He could just be pretending to care about her, but I remember him sobbing and talking about loving her.

shmerl: [warning - some spoilers ahead]

Ongoingwhy:
Reverend is also guilty for kicking his daughter Hela out to the street, when she became pregnant and that caused her to become a whore (you probably know who that is if you finished the game). He was also cruel to Alvin while he lived in Reverend's house. Alvin reveals that only to drunk(!) Geralt when they are in trade quarter. He says, that Reverend used to beat him, while drunk.

Abigail is the most complex character in the chapter IMO. Regarding Odo, it's not clear how she used the doll. Odo himself said, that he saw some beast in her window, and got scared. She could have used it just to scare him off, there is no clear evidence that she made him kill his brother (except his words), and there is no clear motive (unless there is some hidden plot behind, like revenge and etc. but we never know). She on the other hand while being rather cynical about the villagers in general, took Alvin in, showing compassion.

If Abigail is left to be lynched (but that's very out of character for Geralt to do IMO) that path reveals that Abigail is a secret follower of Coram Agh Tera cult, which is banned in Temeria. Followers of that cult use cruel bloody rituals and etc. However in general Abigail appears not to be cruel, and is just very pained by her persecution. Other followers of the cult whom Geralt encounters in the game are way more insane and violent. Abigail feels much better about people in Murky Waters, where villagers are more accepting to strangers.

Also, if Abigail is killed by the mob, later in Murky Waters the plot develops differently, and Geralt is actually blamed for having the innocent blood on his hands (if he consults Murky Waters healer who's there instead of Abigail regarding lifting the noonwraith curse). In that case Geralt can't easily remove the curse from the noonwraith without another life (Adam) being lost. So in retrospect it shows that saving Abigail was the right thing to do.

shmerl: Good points - yes, that's pretty possible that Abigail isn't a follower and that reference is just accidental. As I said, she doesn't look like one and she isn't some maniac.

Actually Abigail mentions that Reverend threw his pregnant daughter out to the street, but her identity is revealed only later on.

IMO it was a right thing to save Abigail since she wasn't guilty in such crimes to be punished that way. But it's made to be not very obvious. It's a question of whether Geralt need to get involved to defend the innocent. Interestingly, he becomes obligated to do so after being knighted by the Lady of the Lake.

shmerl: If you follow her words, she's saying something about safeguarding the helpless.

Also, in the books Geralt finds himself rather often in conflict with the codex (i.e. about not meddling in human affairs), and in practice he doesn't only meddle and helps a lot of people, but as you said angers quite a lot of powerful figures along the way :) In the game Geralt has a lengthy discussion on this subject with Zoltan.

shmerl: Was it the incident in the inn with Shani? Most probably they are talking about Mikul. His reaction to Geralt (poor Ilsa and etc.) when he tells Mikul that he found woman's body in the crypt can be a play, to hide his involvement in the crime. Or may be he already regrets about what happened. The plot itself isn't very clear though. It's possible that Mikul sold Ilsa off to these thugs for some reason.
