Coleman is going to die. How long should I keep him alive?
I let the Scoia'tael take Haren Brogg's weapons in Chapter 1. I looked up what happens with the decision beforehand. But, forgot about it by the time I reached Chapter 2. Before leaving the sewers, I cleared out the Cultists' Crypt, and picked up a bunch of loot. As a result, upon exiting the sewers, I ignored Geralt's comment about the detective's house, and prioritized recovering my items from the jailer and consolidating my inventory. I continued to get side-tracked from visiting the detective for a while. I started Coleman's quest, The Rat, as well as Carmen's quest Working Girls. The location for The Rat is next door to the detective. So, I grouped them together. I saw the detective, fought the Salamandra assassins, cleared the house of ghost for Coleman (and got wine from the cellar for Conrad), took care of the thugs at the Working Girl locations, and returned to The Hairy Bear to talk to Coleman, only to find him dead.
I found out that the Scoia'tael killing Coleman is triggered by seeing the detective, and I was able to revert to an older save. Then, I kept Coleman alive long enough to talk to him at the docks, collect my reward, and get the information to clear Vincent of suspicion. After that, I didn't know how to advance the story further without seeing the detective. So, I turned Coleman in to the inn keeper since he was going to die anyways.
I still have a save from before I turned him in. Is there a reason to keep him alive longer? Does it make a difference with Vincent? How far can I get without seeing the detective?
