Kill all of them in all 3 areas and return to the spirit to complete the quest. They are easy to find, as they are marked on the map. You will be tasked with killing the rest of his crew.
Here's what should be left for this step: You should also focus on any other non-collectable or side quest related trophies you may not have gotten when going through the main quest line.
You can view Harry94's collectable guide here to help. Once you've beaten the game, go back and finish up with any collectables or side quests you may have missed or were unable to obtain or complete at the time because you didn't have the abilities to do so. Here is what you should generally unlock during this step: Just pick whatever difficulty you feel like doing and enjoy the game. I chose normal, and it can still be challenging at times, and I had my fair share of deaths. You can play on whatever difficulty you would like as there are no difficulty-related trophies. There are some collectables that you cannot obtain right anyway until you unlock certain skills anyway. The beauty of this game is that there is nothing missable, so my suggestion is to just play and enjoy the story as you can go back after you finish it and collect whatever you missed.
