As I've previously stated, I firmly believe that anyone who hasn't already completed the entire run of Preacher should NOT be reading any reviews or summaries of these later volumes. All I can safely say is that this is an interlude before the final volume in which nothing big seems to happen, but it's critical for setting the stage of the ending. Also, if you ever find yourself performing oral sex in an alley in exchange for heroin, you might want to take a second look at your life choices. 
 If you have read it already or just like to live dangerously: (view spoiler)[ The main thing striking me as I reread this for like the third time is how much worse Cassidy seems. What he did to Tulip in the guise of 'helping her' after Jesse's apparent death just comes across as sicker and more twisted every time as does the history that Jesse finds when he goes looking into Cassidy's past. 
 Ennis did a masterful job of showing us almost from the beginning that despite seeming like a friend Jesse could count on that he really was a vampire in the truest sense. He charms and seems to offer loyalty when in reality he's a monster who sucks every good thing from the lives of those he gets closest too. And what's really interesting is that Cassidy doesn't even think of it like that. He rationalized his treatment of Tulip as doing what was best for her and even when he's previously confessed some sin to Jesse, it's always been framed as some kind of boys-will-be-boys misadventure. 
 Conversely, the more times I go through this, the less patience I have for the Arseface storyline. It was crudely hilarious the first time through with moments of poignancy, but the joke has gotten stale by now. (hide spoiler)]
